This invention relates to the field of B2B foreign trade website building technology, and in particular to a
content model construction and unified engine execution method,
system, and device. The method includes: the
client configuring fields of the
content model; the
server constructing the fields into a tree-like field structure according to hierarchical relationships, storing the tree-like field structure as
metadata, and assembling a model definition
object based on the read
metadata; the
client recursively rendering the form interface based on the model definition object; the
server generating
data validation rules based on the configuration parameters in the
metadata, and validating the form data submitted by the
client based on the
data validation rules; the
server storing the validated form data according to the field attributes in the metadata, and performing
state management, soft deletion, and sorting
processing on the content data. This invention can solve the problems of high
coupling between model and code,
complex field nesting, difficulty in expansion,
code redundancy, and difficulty in ensuring consistency of state across multiple modules in existing technologies.
