AnQiCMS Help Document and User Guide
In website operations, we often encounter the need to handle various long string IDs, such as product SKUs, order numbers, user IDs, etc.These ID strings usually contain multiple segments of information, and we may only need part of the numbers for displaying on the page, statistics for reports, or for some business logic judgments.AnQiCMS (AnQiCMS) strong template engine provides us with flexible tools, making it easy to meet such needs.### AnQiCMS template string processing tool: Filter AnQiCMS
In website content management, we often need to handle various data, and this data is not always in its final form.Sometimes, we need to perform simple addition, subtraction, multiplication, and division in templates, and sometimes even more complex mathematical operations, such as calculating squares, cubes, or handling complex expressions with multiple steps.For AnQiCMS users, the good news is that its template engine provides very flexible and powerful mathematical calculation capabilities, allowing us to easily meet these needs.The template system of AnQiCMS is based on Django template engine syntax
In website content operation, we often encounter situations where we need to display numbers.These numbers may come from a floating-point type in a database, but in some cases, when they are exactly integers (such as `10.00`, `50.0`), we want them to be presented in a more concise integer form, such as `10` or `50`, rather than with unnecessary decimal parts.AnQiCMS (AnQiCMS) provides powerful template tags and filters, where the `floatformat` filter is a powerful tool to solve such problems
In website content operation, the precise display of numbers is often crucial, whether it is product prices, statistical data, or technical indicators, the accuracy of decimal point display directly affects the accuracy of information and the understanding of users.AnQiCMS provides a flexible template engine that allows us to easily adjust the decimal precision of numbers in frontend templates, thus satisfying various complex display requirements.The AnQiCMS template system is developed based on Go language, with a syntax style similar to Django, it offers powerful Filter (Filter) functions
In website operation, we often encounter the need to handle numerical data such as product prices or service charges.This data is sometimes stored in custom fields, but for various reasons, they may be saved in the form of strings (text), such as "199.50 yuan" or "150".When we need to perform a total calculation on these prices in a template (such as the order total), directly performing a 'sum' operation on the string will yield unexpected results (such as '199.5015.00' instead of '214.50').At this point, it is necessary to convert these string prices into actual numbers
During website operation, we often encounter scenarios where we need to perform calculations on custom data, such as dynamically calculating prices based on product parameters, displaying rating statistics, or performing other numerical processing based on user input or content attributes.AnQi CMS provides us with the ability to meet these requirements with its flexible content model and powerful template engine.This article will introduce in detail how to perform numerical calculations based on custom string parameters in Anqi CMS.### First Step: Preparation - Define Your Custom Parameters First
In website operation, the display of product prices is a crucial link, not only to ensure the accuracy of information, but also to ensure that the presentation method conforms to the reading habits and brand image of users.AnQiCMS with its flexible template system, provides users with powerful customization capabilities, allowing you to easily control the display of product prices, including decimal places.### How to get product price: Where does it come from? In the AnQiCMS template, the product price is usually stored and called as a field of the document (Article or Product)
In AnQiCMS template development, in order to better display and control the presentation of data on the page, we often need to format variables.Among them, the `stringformat` filter is a very practical tool that allows us to convert numbers, strings, or other types of values into a specific string format according to predefined rules.The strength of this filter lies in its adoption of the placeholder syntax of the Go language `fmt.Sprintf()` function, making the control of output format flexible and accurate
In the display of website content, we often need to present different types of data (such as numbers, strings, and even more complex structures) in a unified and precise manner on the page.The template engine of AnQiCMS provides powerful tools, one of which is a very practical feature called `stringformat` filter, which can help us format any value into a string of a specific format.When we retrieve data from the backend, whether it is the number of views of an article, the price of a product, or user-defined parameters, they may be represented by numbers
In AnQi CMS template development, flexibly using various filters (filters) can greatly enhance the efficiency and accuracy of content display.`get_digit` filter is one of the practical tools used to process numeric data.It allows us to extract a specific digit from a number accurately.However, a common issue during usage is: What will the `get_digit` filter return if the position being accessed exceeds the length of the number itself?### `get_digit`
