AnQiCMS Help Document and User Guide
When building a website on Anqi CMS, we often need to flexibly handle and display data in the template.These, `integer` and `float` filters are very commonly used tools when converting values to integers or floating-point numbers.However, have you ever thought about how the system will handle when these filters receive a value that cannot be recognized as a number?In other words, what default values will these filters return if the conversion operation fails?Understanding this is crucial for us to write robust and predictable template logic.###
In AnQi CMS template creation, we often encounter situations where we need to process strings entered by users or retrieved from the database.One common requirement is to determine whether a string can be successfully converted to a numeric type and to perform different conditional processing based on the result.This is crucial for data display, calculation, and even simple form validation.The AnQi CMS template engine (based on Go language's Pongo2) provides a rich set of filters (filters) and logical tags, allowing us to flexibly meet this requirement.

It is crucial to clearly communicate the inventory status of products to users in website operations, especially for sites involving product display.This not only optimizes the user experience, reduces invalid consultations, but also effectively guides the user's purchase decision.AnQiCMS as a flexible and efficient content management system, implements the display of "in stock" or "out of stock" status according to the product inventory quantity in the template, which is very intuitive. AnQiCMS template system adopts a syntax similar to Django, which allows us to control the display of page content through concise tags and variables.When processing product information
In website content operation, the review status of the content is a very important link.Whether it is a comment submitted by the user, a forum post, or an article or product information released by the website administrator, it often needs to be reviewed before it can be displayed to the public.AnQiCMS provides a flexible template mechanism that allows us to easily display different content on the front-end page based on the review status of the content (such as "approved" or "in review"), thereby providing users with clearer and more accurate feedback.AnQiCMS template syntax is similar to the Django template engine
In AnQiCMS template development, displaying list content is a common requirement, and how to elegantly handle the images in these lists, especially thumbnails, is directly related to the visual effects and user experience of the website.The `archiveList` tag is one of the core content call tags of AnQiCMS, which helps us flexibly obtain various document lists.However, in practice, we often encounter situations where certain documents have not set thumbnails, which may lead to broken images or layout confusion on the page. At this time
When using AnQiCMS for website template development, you often encounter situations where you need to display list data, such as article lists, product lists, or image galleries.When we retrieve data through template tags (such as `archiveList` or `categoryList`) and use a `for` loop to iterate over the list, if the list is empty, it is usually necessary to provide the user with a friendly prompt instead of displaying a blank space.How can you elegantly judge whether a list is empty in a `for` loop and display a 'No content' prompt?
In the template development of AnQiCMS, we often encounter situations where the content may not contain images.For example, a news article may not have an illustration, or a certain product in a product list may not have uploaded the main image temporarily.In this case, if the template directly calls the image address, it may display a broken image icon or leave an abrupt blank, which undoubtedly affects the overall aesthetics and user experience of the website.To solve this problem, AnQiCMS provides flexible template tags and filters, allowing us to determine whether the image variable exists
During the development of website templates, we often encounter a headache-inducing problem: when the data obtained from the database is empty (null) or a variable is not defined under certain circumstances, the template rendering will cause an error, resulting in the page not displaying normally and significantly reducing the user experience.AnQiCMS (AnQiCMS) is based on its powerful Go language backend and flexible Django-style template engine, providing us with various elegant solutions for handling such situations, allowing the template to run smoothly even when the data is incomplete.### One, make good use of conditional judgments: `{% if
In web template development, handling the case where variables may not exist or are empty is a common task.The AnQiCMS template system provides a variety of filters to help us elegantly handle such issues, with `default` and `default_if_none` being two commonly used tools.They both provide a default value when the variable is 'no value', but there is a subtle but important difference in the definition of 'no value'.Understanding these differences can help us control the display of template content more accurately.###
In Anqi CMS template design, we often encounter situations where variable values may be empty.For example, an article may not have a thumbnail set or a product field may be temporarily unfilled.If the template directly displays these empty values, ugly blank spaces will appear on the page, affecting user experience, and may even confuse visitors.To solve this problem, Anqi CMS provides a very practical filter mechanism, where the `default` filter is the key tool to ensure the continuity of content display.### `default` Filter
