Anqi CMS, as an efficient and flexible content management system, one of its core advantages is that it provides a highly customizable content model.As an operations personnel familiar with AnQi CMS, I can clearly tell you that you can fully modify the built-in content model of AnQi CMS, as well as create, modify, or delete custom content models.However, these modifications are not without cost, and they will have varying degrees of impact on the content you have published.
Firstly, let's talk about the modifiability of the content model in Anqi CMS.The system is pre-installed with the basic models of 'Article Model' and 'Product Model', which are the cornerstone for constructing the website content framework.For these two built-in models, you can make modifications, but the system does not allow you to delete them directly, ensuring that the website's basic content structure is not accidentally damaged.In addition to built-in models, you can also create brand new custom content models based on business requirements. These custom models offer greater freedom and can be modified or deleted at will.The modification of the content model mainly focuses on the definition of its fields, you can adjust the model name, URL alias, the display style of the content title, and most importantly - custom fields.
Next, we will analyze in detail how these changes will affect the content you have already published.
When you are setting up the content modelAdding new custom fieldsWhen, for example, adding an 'author bio' field to the 'article model', this usually will not cause any destructive impact on the frontend display of existing published content.The content published will be default empty in these new fields, unless you set a default value for them when adding the fields, or manually edit these contents to fill in the new field information.On the template level, if you want to display these new fields on the front end, you need to manually modify the template code to reference these newly added fields.If the template is not modified, the new field will not be displayed on the front end, but this will not cause any display errors for published content.
If you chooseModify the properties of an existing fieldFor example, changing the field type (from single line text to number), adjusting the required status of the field, or renaming the 'Call Field' name, this will require you to be particularly careful.Changing the field type may cause incompatibility issues with existing data, for example, changing the field type from text to numeric may cause the system to fail to handle the existing text data correctly, resulting in data loss or abnormal display.Modifying the required status of a field will only affect the publishing and editing of new content in the future, with less impact on published content, but it is still recommended to check whether existing content meets the new required requirements.It is more important to modify the name of the 'called field' (not the 'parameter name'), as it will directly affect the call to this field in the front-end template.If the template still tries to use the old field names, the related content will not be displayed correctly.
Delete an existing fieldThe impact is more direct and significant.Once you delete a custom field from the content model, the data for that field in all published content will be permanently lost and cannot be recovered.If your website's front-end template used this deleted field to display content, then these templates will not be able to retrieve data, which may result in blank pages, error messages, or disordered layouts.Therefore, it is strongly recommended that you carefully check all related template files before deleting any fields, confirm whether the field is still in use, and consider backing up the database.
Delete the entire custom content modelIs the most severe operation.When you delete a custom content model, all categories associated with that model and all sub-documents under those categories will be permanently deleted. This is an irreversible operation.The built-in model cannot be deleted, but if its custom fields are deleted, it may also lead to the loss of a large amount of content data.Be sure to confirm multiple times and perform a complete database backup before performing such operations, just in case.
FromTemplates and content displayFrom this perspective, any modification to the content model may require you to synchronize the update of the front-end template. The template design of Anqi CMS is highly dependent on the structure of the content model, whether it isarchiveDetail/archiveListOrarchiveParamsAll labels, are obtained and displayed through model fields.Field addition, deletion, and modification all mean that the corresponding code in the template may need to be adjusted to ensure the correctness and aesthetics of the content.
In addition,SEO and URL structureMay also be affected.If your rewrite rules or custom URL settings include the URL alias of the content model or certain fields, then modifying these models or fields may cause the URLs of existing content to change.Although the Anqi CMS provides 301 redirect management functionality, you still need to manually configure or check to avoid a drop in search engine rankings or loss of traffic due to URL changes.
In conclusion, the content model of Anqi CMS provides great flexibility, but this flexibility also comes with responsibility. Before making any model modifications, especially when modifying built-in models or custom models containing a large amount of content, it is recommended that you always follow the following principles:
- Backup first, then operateBefore making any structural changes, make sure to fully backup your database and website files.
- Verify in the test environment firstIf conditions permit, it is best to make modifications and perform tests in a test environment that is consistent with the production environment, ensuring that all functions work normally and the template displays correctly.
- Advance planning and communication: Clearly define the purpose of the modification, assess potential impacts, and communicate thoroughly with relevant personnel such as content editors and template developers.
By meticulous planning and detailed operations, you can fully utilize the flexible content model of AnQi CMS to create the most suitable content structure for your website.
Common Questions (FAQ)
Q1: What is the impact of modifying the "model table name" or "URL alias" of the built-in content model?
Q2: Can I recover if I accidentally delete a field in the custom field?It is regrettable that once a custom field is deleted, all the published content associated with that field will be permanently deleted. The Anqi CMS system does not provide a direct function to restore deleted field data.This is why we emphasize the necessity of being cautious and confirming, as well as performing a database backup, before carrying out any field deletion operations.If you have a database backup, theoretically you can try to recover the data through database recovery, but this is usually a complex process.
Q3: How to troubleshoot after the content model is modified and the front-end display of the website appears abnormal?Firstly, you should check whether the fields used in the front-end template were deleted when modifying the content model.If deleted, the template will be unable to retrieve data and cause an exception.Next, confirm if you have changed the field type (e.g., from text to number), as incompatibility between existing data and the new field type may also cause display errors.Finally, after any model modification, be sure to clear the system cache of the Anqi CMS to ensure that the front-end is calling the latest configuration and data.If the problem still exists, check the server error logs or browser console for more specific error messages that may help you locate the issue.
