Force-escape HTML characters: forceescape
The forceescape filter escapes HTML special characters (&, <, >, ", ') just like the escape filter, but it enforces escaping even on strings that have already been marked as safe. Normally, once a string is marked safe with the safe filter, escape will not escape it again. The forceescape filter overrides that behavior.
This is useful when you need to guarantee that a value is escaped regardless of how it was produced earlier in a template chain. For example, if a value was marked as safe somewhere upstream but you want to display it as literal text rather than rendered HTML, forceescape ensures it gets escaped.
Usage
Here’s how to use this template function. Copy any example and adjust it to your setup.
{{ "<b>bold</b>" | safe | forceescape }}
<b>bold</b>
Function signature
The signature is a technical summary of this template function. It shows the name of the function, the values (called parameters) it accepts, and what type of data each parameter expects (for example, a piece of text or a number).
Function parameters that have a = with a value after them are optional. If you leave them out, the default value shown is used automatically.
Function parameters without a = are usually required. A few optional parameters have no default value, so the signature shows them without a = as well. To check whether a parameter is required, look at the parameter list below the signature. Each parameter is marked as Required or Optional.
The most common optional parameter without a default value is default. The default parameter sets the value a function returns when the function can’t produce a result, for example, when float gets text that isn’t a number. If you leave out default, there is no fallback value, so most functions raise an error and the template fails. The parameter list of each function says what happens. If you set default, the function returns your value instead.
How to read a signature
Here is the signature of the round filter as an example:
round(
value: Any,
precision: int = 0,
method: str = "common",
default: Any,
) -> float | int | Any
-
roundis the name of the function. - Between the parentheses are the parameters. Each parameter has a name, followed by a colon and the type of value the parameter expects. The type only tells you what kind of value to pass. For
default: Any, you pass a value of any type, such as0or"unknown", not the wordAny. -
= 0and= "common"are default values. You can leave outprecisionandmethod, androunduses these default values. -
defaulthas no=, but the parameter list marksdefaultas optional. If you leave outdefaultandroundgets a value that isn’t a number,roundraises an error. -
->shows the type of value the function returns. - Inside a signature,
|means “or”. This function returns a decimal number, a whole number, or the value you passed asdefault.
round is a filter, so the first parameter, value, is the value before the |. For example, {{ 3.14159 | round(2) }} returns 3.14.
The types you’ll see most often:
-
str: text, such as"hello" -
int: a whole number, such as5 -
float: a decimal number, such as3.14 -
bool:trueorfalse -
list: a list of values, such as[1, 2, 3].list[str]is a list of texts. -
dict: a set of keys and values, such as{"name": "Kitchen"} -
datetimeandtimedelta: a date and time, and a duration. For details, refer to Dates and times. -
None: no value -
Any: any type of value
Some signatures use special forms:
-
*argsmeans you can pass any number of values, separated by commas. For example,average(1, 2, 3). -
value | name(...)means the function is a filter. The value before the|is passed to the filter as its first parameter. Some filter signatures, like theroundexample, show this value as the first parameter between the parentheses instead.
