to a variable that would normally have auto-escaping applied to the result will only result in one round of escaping being done.
So it is safe to use this function even in auto-escaping environments.
This tag is particularly useful in a loop: From then on, you can insert the current value of the cycle wherever you’d like in your template by referencing the cycle name as a context variable.
If you want to move the cycle to the next value independently of the original that initiates the cycle will itself produce the first value in the cycle.
In this example, both “o” and “f” are backslash-escaped, because otherwise each is a format string that displays the year and the time, respectively: Any valid template lookup is a legal grouping attribute for the regroup tag, including methods, attributes, dictionary keys and list items.
For example, if the “country” field is a foreign key to a class with an attribute “description,” you could use: .
This could be a problem if you want to use the value in a nested loop or an included template.
Blocks are evaluated Note that you can backslash-escape a format string if you want to use the “raw” value.
This will work on some data types (strings, list, etc.) and fail on others. For example, if we have: Takes a list of dictionaries and returns that list sorted in reverse order by the key given in the argument.
This works exactly the same as the above filter, but the returned value will be in reverse order.
Sometimes that is better for clarity anyway, for the sake of those who do not know the precedence rules.
The comparison operators cannot be ‘chained’ like in Python or in mathematical notation.
For such expressions, it can be important to know how the operators are grouped when the expression is evaluated - that is, the precedence rules.
