It is similar to the Django template engine. If you have any comments or questions, feel free to post them on the source of this page in GitHub. The for expression is used to iterate over a data collection filter sorts them. Jinja.

Jinja, or at least my example, wants to load a Python module and thus there is a directory called These template files overwrite specific Then it is only a matter of opening the file for writing and then writing out the string created by the parameter to the in a template. The rendering examples/python/jinja-skeleton-flat/generate_from_filesystem.py examples/python/jinja-skeleton-flat/templates/index.html In our example, the result is saved in the 'html' directory and it looks like this: examples/python/jinja-skeleton-flat/html/index.html If you would like to support his freely available work, you can do it via In our example, the result is saved in the 'html' directory and it looks like this: In the next example, we create a simple Flask application that uses parts. which is loaded with is printed to the user. For instance, A template contains variables and/or expressions , which get replaced with values when a template is rendered ; and tags , which control the logic of the template. are often used to generate large amounts of emails, in source code

The dynamic parts are later replaced with data.


more convenient. blocks of the base template file. By convention, they live in the /templates directory in a Flask project. and improves code organization.
preprocessing, or producing dynamic HTML pages. Jinja allows a convenient dot notation to access data in Python A template engine or template processor is a library designed to … In this tutorial, we have covered Python Jinja module. Jinja can generate any text-based format (HTML, XML, CSV, LaTeX, etc.). We have a list of car dictionaries. We show the person's name and age. function later combines the templates with data. Now we do not use a simple string template anymore. object. the collection.

Conditionals are expressions that are evaluated when a certain Template inheritance is a powerful feature that reduces code duplication Jinja is a modern and designer-friendly templating language for Python, modelled after Django’s templates. The template engine is similar to the Python The example prints only minor persons; a minor is someone younger than 18. Every time though I have to spend some time figuring out how to lay out my files and how to load the template. In the template file, we use the for expression to iterate over In the template, we output only persons younger than 18 using A template engine or template processor is a library designed to combine Each dictionary has a price key. Jinja deals with "environments", hence we import the In the first example, we create a very simple template.

We can work with objects in our template strings. The example asks for a user name and generates a message string, which the sum filter can sum data, escape filter escapes them, and sort If you’re familiar with string formatting or interpolation, templating languages follow a similar type of logic—just on the scale of an entire HTML page. Welcome to a Flask tutorial covering a bit more about Jinja. The template string renders two variables: name and age. dictionaries. White space in output can be controlled with environment attributes. Note: Jinja Templates are just .html files. next to the % characters is used to control white space. We have a person dictionary. A possible usage for rendering an HTML file is the avoidance of writing duplicate code. Finally, just for completeness, let's see how the generated HTML file looks like:

The dot notation is Template engines Jinja uses various delimiters in the template strings.
