Description of the Drawings

[0052] In order to more clearly illustrate the technical solutions in the embodiments of the present specification or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments recorded in the present specification. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings. In the drawings:

[0056] The embodiments of the present specification provide a method, device and equipment for calculating an expression with custom update.

[0057] Currently, with the diverse development of system application scenarios, developers need to develop corresponding software for the needs of different enterprises to solve corresponding demand problems. When facing the same project problems that need to be solved by different enterprises, since the business of each enterprise is not static. Therefore, when the business data changes, even if only a change in a certain version model is involved, developers need to start developing the software from scratch, wasting a large amount of R & D time. For example, scenarios such as field calculation and spatial display and hiding control involved in the software development process can be involved in various businesses. Although the development difficulty is not great, it takes a lot of development time, and after problems occur, it is also necessary to debug and modify one by one, which not only causes a waste of R & D time but also cannot adapt to the replacement of various business scenarios.

[0058] To solve the above technical problems, the embodiments of this specification provide a method for calculating custom-updated expressions. By determining whether there are expressions related to business data in the preset expressions, it is determined whether second developers need to edit the expressions according to the business data. At the same time, based on the dependent data, the existing expressions in the preset expressions are updated, avoiding the process of re-writing in the traditional technology and saving the software development time. In addition, the description file of the expression, the current form context data, and the expression execution engine communicate in a preset interface manner, making the calculation and execution process of the expression have great flexibility and scalability.

[0059] To enable those skilled in the art to better understand the technical solutions in this specification, the following will clearly and completely describe the technical solutions in the embodiments of this specification in conjunction with the accompanying drawings in the embodiments of this specification. Obviously, the described embodiments are only a part of the embodiments of this specification, rather than all the embodiments. Based on the embodiments of this specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this specification.

[0060] As Figure 1 shown, the embodiments of this specification provide a flowchart of a method for calculating custom-updated expressions.

[0061] The execution subject in the embodiments of this specification is the server that needs to update the expression or each execution unit of the server. It can be Figure 1 seen that the method steps include:

[0062] S101: Obtain the business data to be processed, determine the current form corresponding to the business data to be processed, and determine the expressions related to the business data;

[0063] With the development of big data, more and more scenarios require processing of business data. For example, in scenarios involving field calculations, control display and hiding control, control read-only, field mandatory, field verification, etc., although the development scenarios are simple, developers still need to adjust parameters one by one, consuming a large amount of development time. In one or more embodiments of this specification, in order to save development time, after obtaining the business data to be processed, the current form corresponding to the currently to-be-processed business data is first determined, so as to facilitate obtaining the data and context data required for expression calculation according to the current form subsequently. At the same time, in order to save developers from repeating the development of expressions, it is necessary to determine the expressions related to the business according to the business data, that is, to determine the calculations to be performed and the values to be obtained according to the business data. It should be understood that the calculations to be performed, the values to be obtained, and the rule logics to be carried out for the business data are all based on expressions.

[0064] After determining the expressions related to the business data, if some of the expressions related to the business data do not exist in the preset expressions, then the on-site secondary development personnel need to write the relevant expressions that do not exist in the preset expressions according to the business requirements. The specific writing process is as follows: First, obtain the business rules contained in the business data and the context data of the current form, and then perform rule parsing on the business rules contained in the business data and the context data of the current form according to the preset parsing rules to obtain the operations that the business data needs to perform, such as the processing steps required by the business data, the association relationships between the processing steps, and the storage logical relationships of each data. Then, obtain the expression designer corresponding to the version according to the system version contained in the business data, and input the operations that the business data needs to process into the corresponding expression designer to obtain the expression to be updated corresponding to the business data.

[0065] It can be understood that the obtained expression to be updated is the expression related to the business data that does not exist in the preset expressions. After obtaining the dependent data of the expression to be updated, the dependent data of the expression to be updated is updated according to the current dependent data in the current form, so as to obtain the updated expression that conforms to the business data to be processed. The context data of the current form records the data associated with the updated expression. Therefore, by calculating the updated expression, the calculation result obtained is the data required by the business data, and executing the calculation result on the corresponding control completes the execution of the expression and realizes the requirements of the business data.

[0066] S102: If the relevant expression exists in the preset expression, determine the dependent data of the relevant expression based on the preset form of the preset expression.

[0067] For example, taking a calculation expression as an example, its entity structure is shown in Table 1 below: where the Fee field is read-only and its value is Price * Qty; therefore, the expression is written as: return SalesOrder.Price * SalesOrder.Qty; and the dependent data of this expression is shown in Table 2 below as SalesOrder.Price and SalesOrder.Qty.

[0068]

[0069] Table 1. Entity Structure of Expression in a Certain Application Scenario

[0070]

[0071] Table 2. Dependent Data of Expression

[0072] S103: If it is determined that the dependent data has changed based on the current form, obtain the updated data of the dependent data and the context data of the current form.

[0073] The above step S101 records the process of customizing the calculation of the expression in the scenario where the relevant expression does not exist in the preset expression. When there is an expression related to business data in the preset expression, it is necessary to determine the content of the expression based on the entity structure to which the expression applies, the function of the expression, and the form context data, and then output the corresponding description file according to the expression content. The description file records the data essential for implementing business data. For example, if data needs to be stored, the description file can be the model, memory, etc. of the mobile phone. Input the entity structure, the function of the expression, and the form context data into a pre-set expression designer, and then the corresponding description file can be obtained according to the pre-set expression designer.

[0074] After obtaining the description file, obtain the expression corresponding to the description file. Then, determine the dependent data of the corresponding expression according to the expression content such as the entity structure to which the expression applies, the function of the expression, and the form context data in the corresponding expression. If it is determined that the dependent data of the corresponding expression has changed relative to the dependent data of the preset expression, then it is necessary to obtain the updated data of the dependent data and the context data of the current form to perform the update calculation of the expression. It should be noted that the description file includes a first interface and a second interface, enabling the description file to communicate with the form context through the first interface to achieve the update of the description file. The second interface communicates with a preset expression engine, and then the description file obtains the corresponding expression.

[0075] S104: Determine the expression to be updated for the relevant expression based on the updated data and the context data of the current form, and calculate the calculation result of the updated expression.

[0076] When it is determined that the dependent data has changed, in order to ensure the normal operation of the business, the corresponding expressions that depend on the dependent data need to be updated synchronously. For example, for the content in Table 1 and Table 2 above, when it is monitored that SalesOrder.Price or SalesOrder.Qty has changed, and it is found that there is an expression SalesOrder.Fee that depends on these two data, then the expression SalesOrder.Fee needs to be updated based on these two data to obtain the calculation result that conforms to the business data. Among them, determining the expression to be updated based on the updated data and the context data of the current form, and calculating the calculation result of the expression to be updated specifically includes the following steps:

[0077] First, according to the preset interface of the preset expression engine, obtain the expression corresponding to the description file. For example, if the content in the description file shows data related to the profit of this year, then the expression corresponding to the profit calculation is required. Then, according to the context information of the current form, determine the expression that the current form should execute in the corresponding expression. According to the name of the updated data, search for the expression associated with the updated data in the obtained expression to be executed, and use the associated expression as the expression to be updated. Then, obtain the expression function that depends on the current updated data from the expression to be updated, and replace the data with the same name as the updated data in the expression function, so as to calculate the calculation result of the expression to be updated based on the context information of the current form.

[0078] In one or more embodiments of this specification, after obtaining the calculation result of the expression based on the updated data and the context data of the current form, in order to apply the expression to the correct action control to achieve the business requirements, first obtain the preset expression application strategy of the action control that stores various expressions, and then determine the application strategy that conforms to the current expression according to the business requirements and the preset expression application strategy. Thus, according to the current expression application strategy, use the preset expression execution engine to apply the calculation result to the corresponding space to complete the update of the expression.

[0079] In addition, in one or more embodiments of this specification, after the update of the expression is completed, in order to update the controls associated with the control corresponding to the expression, first, according to the data object associated with the corresponding control, the running operations associated with the data object are determined, and then the controls associated with the associated running operations are obtained. It should be noted that the controls associated with the control corresponding to the expression are one or more controls of the current form. After the associated controls are obtained, the associated running operations are executed according to the updated data to obtain the corresponding running results, and the data of the associated controls are updated according to the running results.

[0080] In addition, in order to debug and modify the expression update process, the execution process of applying the calculation result to the corresponding control by the preset expression execution engine is added to the preset log library, so that both the writing and execution processes of the expression can detect the calculation process of the expression based on the preset log library, ensuring the correct update of the expression.
