Jinja filter Section n n The filter section in Jinja2 allows you to apply one or more filters to an entire block of content, rather than just a single variable. This is a powerful and elegant way to perform transformations on a large section of your template, which helps keep your code clean and avoids…
Jinja call Block n n The **call block** in Jinja2 is a special construct that allows you to pass a segment of template code to a macro. This is extremely useful for creating reusable container-style macros that wrap content with a consistent structure, like a dialog box, a panel, or a card component. nn n…
Jinja Macros Introduction n n Macros in Jinja2 are powerful tools for creating reusable code snippets, much like **functions in regular programming languages**. They are a cornerstone of the “Don’t Repeat Yourself” (DRY) principle, allowing you to define a template element once and reuse it across your project, saving time and ensuring consistency. nn n…
Jinja Control Structure: for Loop with Dictionaries n nnThe for loop is a versatile control structure in Jinja that allows you to iterate over various data types, including dictionaries. As variables in templates retain their object properties, it is possible to iterate over containers like a `dict` to access its keys and values. This is…
Jinja2 Literal Expression: Booleans n nnA boolean literal represents a value that is either true or false. These are fundamental for controlling program flow and logic in your templates. The values `true` and `false` are always lowercase. For consistency with Python and to avoid past confusion, you can also use True and False, but the…
Jinja Literal Expression: Dictionaries n nnA dictionary is a structure that combines unique keys and their corresponding values. In Jinja2, a dictionary literal is created with a set of curly braces containing comma-separated key-value pairs ({key: value}). Keys must be unique and always have exactly one value. While dictionaries are not as frequently used in…
Jinja Literal Expression: Tuples n nnA tuple is a sequence of comma-separated values, enclosed in parentheses ((…)). The key difference between a tuple and a list is that a tuple is immutable, meaning its contents cannot be changed after it is created. Tuples are generally used to represent a fixed collection of related items, such…
Jinja Literal Expression: Lists n nnA list literal is a sequence of comma-separated values, enclosed in square brackets ([…]). Lists are useful for storing sequential data that you need to iterate over, such as a collection of items, user accounts, or navigation links. Lists are also mutable, meaning you can change their contents.nn nn How…
Jinja Literal Expression: Floats n nnA floating-point number, or float, represents a number with a decimal part. Floats can be written using a period (.) as a decimal mark and can also be written in scientific notation using an uppercase or lowercase e to indicate the exponent. The underscore character (_) can be used to…
Jinja Literal Expression: Integers n nnAn integer literal is a whole number without a decimal point. Integers are a fundamental data type in Jinja2 used for counting, performing arithmetic, and controlling logic in your templates. For improved readability, the underscore character (_) can be used as a visual separator for large numbers, similar to how…
