What do the `module_id` and `category_id` fields represent in the document details, and can you further query model or category details through them?

Reveal the details of the Anqi CMS document inmodule_idandcategory_idWhat do they really mean?

When using Anqi CMS for content management and website operation, we often obtain various data through API interfaces, including the document detail interface (/api/archive/detailIt is the key to obtaining the core information of a single article. You may notice this in the returned data of the interface.module_idandcategory_idThese fields. They may seem to be just ordinary numeric IDs, but in fact, they are important clues for understanding the structure of the content and for efficient data operations.

Next, let's delve into the meanings of these fields and how they help us better utilize the Anqi CMS for content operation.

module_id: The 'ID card' of the content model

In AnQi CMS,module_idRepresents the 'Content Model ID' of the document. The content model is the foundation of AnQi CMS flexibility, defining the basic structure and expandable fields of a category of content.For example, you might have a "article" model to publish news and blogs, a "product" model to display goods, and even a "case" model to present project experience.Each model has a unique ID.

From the document details interface (/api/archive/detail) we can see thatmodule_idthe field clearly indicates which content model the current document belongs to. For example:

{
  "code": 0,
  "data": {
    "id": 1,
    "title": "欢迎使用AnqiCMS",
    "module_id": 1, // 这里就是文档模型ID
    "category_id": 1,
    // ... 其他文档信息
  },
  "msg": ""
}

Then, thismodule_idCan it be used to further query the details of the model?

The answer is affirmative!

This includes the model name (title), the additional table name (table_name), and most importantly - all the custom fields defined under the model (fieldsThese custom fields define the unique attributes of the content, such as 'product model' may include 'price', 'inventory', etc., and 'article model' may include 'author', 'source', etc.

For example, you can according tomodule_idRetrieve model details and then render the unique filtering conditions of the model (such as through/api/archive/filtersan interface, which also needsmoduleIdparameters).

category_id: Navigation card of content categories

withmodule_idsimilar,category_idThe field indicates the "Category ID" of the document. Categories are the basic way of organizing content, which helps us to organize a large amount of content, making it convenient for users to browse and find.Under a content model, there can be multiple categories, and the categories can form a hierarchical relationship (for example, under the "News" category, there can be "Company News" and "Industry Dynamics" subcategories).
