QUESTION
i'm using python, flask, jinja to make a form, i'm iterating through a list of fields to render the inputs, all is well.
i'm trying to use the field.label attribute as default value in the input boxes so that i don't need labels next to them, but instead of the actual label i'm getting (for a field with label = search_term) inside the input, and Search Term"> next to it...
if i place {{field.label}} anywhere else it correctly displays the field label, and if i use field.name as a value it works fine - why is it acting strangely only within the context of {{ field (class="col-6 text-center", value=field.label)}}?
thanks!

QUESTION
Problem printing ${el }, I want to print the content of the element but it prints $%7Bel%7D. It seems that the jinja detects the component ${el} as its variable.
...ANSWER
Answered 2022-Apr-11 at 09:00You are mixing server-side rendered templates with client side rendered templates. They cannot work together like this, because they have different runtime environment. We need to store the URL prefix in a JS variable and use only JS variables during the forEach loop that runs on the client side:
QUESTION
I am having problem with setting up logic for if statement in HTML template with Jinja.
What should I input in place of ??? in the below code?
I don't want the user to be able to post empty field, therefore, I have decided to disable the submit button while the textarea is empty (e.g.: it has different css style with the form__submit__disabled class).
I have tried inputting in the ??? place content, entry, form__textarea, but it doesn't work.
ANSWER
Answered 2022-Apr-08 at 21:12A better idea, for this requirement would be to use the required attribute of the textarea, and let the browser do the job of warning the end user that this field should be filled in before submitting.
QUESTION
I need to update records in a database table using Ansible, the value I need to put in the field is in the form : ["\/{{name}}"] where name is a variable.
So, if the value of name is Alex the updated value of the url column will be exactly ["\/Alex"].
I am doing this as below:
...ANSWER
Answered 2022-Mar-25 at 00:09It seems you actually have to cast your name variable in a string, otherwise, Jinja is somehow interpreting your list item as a set — {'\/Alex'} is a set in Python.
So, your correct syntax would be:

With this playbook
...ANSWER
Answered 2022-Mar-24 at 20:21Because you did install Ansible with the pip packages ansible-core & ansible-base, you don't have the collection community.general, which this filter is part of.
You have multiple options:
- Install the missing collection, when logged in with the problematic user:

I am using a Jinja filter in ansible to extract the value I need in the right format to process it.
This is the data in JSON format (I have shortened the output, usually there are much more variables per item and not all item have an IPv4 variable et all):

QUESTION
I was reading the ansible document and then it said:
Beginning in version 2.8, attempting to access an attribute of an Undefined value in Jinja will return another Undefined value, rather than throwing an error immediately. This means that you can now simply use a default with a value in a nested data structure (in other words, {{ foo.bar.baz | default('DEFAULT') }}) when you do not know if the intermediate values are defined.
I can not understand it well. Is it said the expression "{{ foo.bar.baz | default('DEFAULT') }}" will be 'DEFAULT' when foo.bar.baz is not defined or it is said the expression "{{ foo.bar.baz }}" will be another value(mark it as VALUE) when foo.bar.baz is not defined and we need to defind another optional or seccond value like default('DEFAULT') in order to avoid making the expression return VALUE that we do not what it will be at all?
The url containing the statement is at: https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#omitting-parameters I got the quotation by a little mouse wheel rotation.
...ANSWER
Answered 2022-Mar-03 at 08:15The important part of the statement is in the "when you do not know if the intermediate values are defined".
Prior to 2.8, if you had:
QUESTION
so I'm working on a website with flask/jinja + tailwindcss. I have this html with a tiny bit of js for state management. Currently the sidebar just appears in it's full state instead of animating in like I want it to.
There's also a codepen if you want to look at that
...ANSWER
Answered 2022-Feb-22 at 06:30So as it turns out, you need to toggle w-full class instead of toggling w-0 class. because otherwise it doesn't want to animate.

Install jinja
You can use jinja like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
