DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0018] The present invention discloses a form engine-based printing template generation method, device, equipment and medium, which can be used in a computer. The method, device or computer-readable storage medium involved in the present invention can be integrated with the above-mentioned device or can be relatively independent.

[0019] A specific embodiment of the present invention discloses a method for generating a printing template based on a form engine, which can be executed by a computer, and specifically by one or more processors of the computer. Figure 1 is a flowchart of a method for generating a print template based on a form engine provided by an embodiment of the present invention. Figure 1 , the printing template generation method based on the form engine includes: S101, obtaining data to be printed, performing metadata modeling on the data to be printed, and obtaining metadata and a metadata interface; S102, based on the metadata, a printing model is established through a form engine, and a custom interface is generated; S103, creating multiple printing templates corresponding to the printing model through the template designer, and generating a printing button; S104: Calling a print rendering engine based on the print button, and combining the to-be-printed data obtained based on the metadata interface and the custom interface with the print template through the print rendering engine to render a print page.

[0020] Among them, through metadata modeling, a database of printing data is established to determine the corresponding relationship between the data to be printed and the metadata. The data to be printed includes user-filled data and external data.

[0021] Compared with the prior art, the printing template generation method based on the form engine provided in this embodiment obtains the data to be printed, performs metadata modeling on the data to be printed, obtains metadata and a metadata interface, establishes a printing model based on the metadata through the form engine, and generates a custom interface. The data is dynamically processed and displayed through the form engine, avoiding the tedious manual update. A plurality of printing templates corresponding to the printing model are created through a template designer, and a print button is generated, so that the generation of documents becomes fast and efficient, and there is no need to manually create or modify documents one by one, thereby improving work efficiency. After the printing template is completed, updating the data only requires modifying the data source, and there is no need to repeatedly open the typesetting software for editing, thereby simplifying maintenance work. After the data to be printed obtained based on the metadata interface and the custom interface is combined with the printing template through the printing rendering engine, a printing page is rendered, and the data to be printed is filled into the printing template, thereby reducing errors caused by manual input.

[0022] In some embodiments, in step S101, the data to be printed is obtained, the data required for printing is entered into the system, metadata modeling is performed on the data to be printed to build a database of printing data, and metadata and metadata interface are obtained, wherein the data to be printed includes user-filled data and external data, and a database of printing data is established through metadata modeling, and the corresponding relationship between the data to be printed and the metadata is determined. For a schematic diagram of metadata modeling, please refer to Figure 2 .

[0023] In some embodiments, in step S102, based on the metadata, a printing model is established through a form engine to obtain user-filled data corresponding to the metadata, and the user-filled data is saved in a database to establish a printing model, that is, to establish a custom user-filled model to facilitate user data filling. After the user data is filled in, it corresponds to the metadata one by one, and the user data is stored according to the corresponding relationship between the user data and the metadata. For a schematic diagram of the printing model, please refer to Figure 3 .

[0024] In some embodiments, in step S103, after obtaining the data required for printing through the printing model, multiple printing templates corresponding to the printing model are created through the template designer, and a print button is generated. The specific process is: obtain components, associate the components with metadata, arrange the components through the template designer, generate multiple printing templates corresponding to the printing model, drag the components to the template designer, and arrange different components in the template designer to form multiple printing templates, that is, one printing model corresponds to multiple printing templates, and users can select different printing templates according to actual needs. The print button can be bound to different printing templates to achieve different printing effects; please refer to the schematic diagram of the printing template. Figure 4, components are associated with metadata, which is convenient for users to use the print template. The backend will directly return data and fill the returned data into the print template. Its components include at least text, picture, rich text, page body, print container, form, text input box, amount input box, text field, custom archive, cascade selection, advanced cascade selection, date selection, electronic signature, data table, editable table, description list and description list item. Among them, when the print template is multiple pages, use the print container in the component to create multiple pages for the print template. The print container is created in the case of manual paging, which can be understood as a sheets of paper. In the case of automatic paging, it is understood that a lot of content is printed on multiple sheets of paper. Through the print container, configure the paper size, paper orientation, paging mode, print margins, mixed horizontal and vertical printing, and page repeat printing. Configure the paper size according to the needs, set the paper to A4 or A3, etc., and set the paper orientation to horizontal or vertical; configure the paging mode to set the paging mode to manual or automatic. If it is automatic, the page will be automatically paginated according to the content when printing. If it is manual paging, you can always create new pages. Each page is printed as one sheet of paper. You need to manually control the page content not to be too long, otherwise It will be truncated when printing. If there is an overlap that is not truncated, you need to manually set the overflow: hidden of the style, and mixed horizontal and vertical printing is not possible in automatic mode; by configuring the print margin, set the distance between the content inside the paper and the edge of the paper, the unit is centimeters; when configuring mixed horizontal and vertical printing, if you print multiple sheets of paper, the direction of one or several sheets of paper is different from the main direction (the direction of the first sheet of paper is taken as the main direction by default), you need to manually set the paper direction of these papers, and set the orientationMix of these papers with different directions to true; when configuring page repeat printing, if there are multiple identical data that need to be printed on multiple sheets of paper, you need to set this property to true and provide a unique identifier, such as repeatPage. The value corresponding to this page is an array, which contains an object containing all the values ​​of this page. The repeatPage object is: repeatPage: [{key1: value1, key2: value2}{key1: value3, key2: value4}]; set a unique name for the print container, such as printpage1, request When returning data, you need to set the value of this name to an array, such as printpage1: [{xxx}, {xxx}]. All elements in this page will take values ​​from the object in printpage1. The object must contain the values ​​of all elements in this page. If the server returns empty, you need to add it manually.The body content Key specifies the data of the page as the body data. If the body data does not exist, this page will be hidden. It is mainly used for table / text content paging. If the content is less than or equal to 3 pages, a 3-page template needs to be created. The second and third pages can be hidden when there is no content. ;

[0025] In some embodiments, in step S104, after obtaining the print template, the corresponding print template is selected according to user needs, and the print template is bound to the print button in the print model to obtain the print template selected by the user, and the selected print template ID is determined. After binding the print button to the ID of the print template, the print rendering engine is called based on the print button, and the metadata interface and the custom interface are called by the print rendering engine to obtain the data to be printed, that is, metadata is called based on the metadata interface to obtain the user-filled data corresponding to the metadata; external data is obtained based on the custom interface, and the external data is data not in the metadata, and the data to be printed is obtained based on the user-filled data and the external data. After combining the data to be printed with the print template, the UI corresponding to the print template is rendered to dynamically generate a print page; after obtaining the data and the print template, the print rendering engine combines the two, matches the components corresponding to the data according to different input data, renders the corresponding UI, and constructs a dynamically generated print interface. The workflow of the print rendering engine is as follows: const renderDom=({ uiTree, uiProps, components, appMode, checkPerm}: IDomTreeProps)=>{, const tmpSchemaData=Array.isArray(uiTree) ? uiTree:[uiTree]; return tmpSchemaData.map((schema)=>{; const { type, children}=schema; let childView: ReactChild | ReactChild[] | null = null; if (children&&Array.isArray(children)) {; childView=isTextNode(children)? children: renderDom({uiTree: children, uiProps, components, appMode, checkPerm}); Among them, renderDom is a constant function that accepts an object containing multiple properties as a parameter. These properties include uiTree: an object or array that describes the component structure. Each object represents the definition of a component, including the component type, properties, and subcomponents; uiProps: a collection of component properties that can provide specific properties for each component; components: an available component map, which obtains specific React components through the component type; appMode: the mode of the application, such as design mode or runtime mode; checkPerm: a permission check function used to verify whether the user has permission to access a component; Convert uiTree to an array If uiTree is an array, use it directly; otherwise, wrap it in an array; The specific process is: use the map method to traverse the tmpSchemaData array, generate a React element for each schema (each component definition), extract type (component type) and children (subcomponents) from the current schema, initialize childView to null to store the rendering results of subcomponents, check whether children exists and is an array, if children is a text node, assign it directly to childView, otherwise, recursively call the renderDom function to render the subcomponent, call the getWidgetKey function to get the unique identifier widgetKey of the current component, get widgetId from the current schema, which is the unique key of the component, get the actual React component of the current component according to the schema and components mapping, get the properties of the current component from uiProps, and if the current component is an HTML tag, create one An htmlProps object containing the tag name; otherwise, it is an empty object. A design object is created. The design object contains the design-related properties of the component, such as widgetKey and widgetId. In design mode and runtime mode, check whether the current component is of Button type, and check the permission through the checkPerm function. If there is no permission, it returns null and does not render the component. Check whether the current component type is NO_OBSERVER_COMPONENTS, which means that these components in the array do not require observers. If it is a non-observable component, render the component directly and pass in the corresponding properties and subcomponents. If it is a component that needs to be observed, wrap the component with Observer so that it can be automatically updated when the state changes, pass in the corresponding properties and subcomponents, and after the map function ends, return a React element (or element array) that corresponds to the component definition in the original uiTree. The final element structure will reflect the required UI component hierarchy.

[0026] After selecting a print template, there will be a print button on the front page of the corresponding print model. Click the print button to print out the information the user wants according to the bound print template and unify the format.
