I have a jinja2 code in my
base.html
{% block body %}]
{% block messages %}
{% with messages = get_flashed_messages(with_categories=true) %}
{% if messages %}
{% for category, message in messages %}
<div class="alert alert-{{ category }} alert-dismissible">
<button type="button" class="close" data-dismiss="alert" aria-
label="Close"><span aria-hidden="true">×
</span></button>
{{ message }}
</div>
{% endfor %}
{% endif %}
{% endwith %}
{%endblock messages%}
{% endblock body %}
and in the
entry.html
{% extends "base.html" %}
{% block body %}
Body text goes here
{% endblock body %}
The problem is until I don't manually call super() in the messages block from the child template jinja2 doesn't display the flash messages.
I'm a total beginner so I maybe completely wrong about how nested blocks work. Can I call the flashed messages without calling super()?? .

I've been stuck on this for a while, can't seem to fix the error. I've checked the code a hundred times but obviously there is something I'm missing. I have installed my app also.
Can anybody see what I'm missing?
views.py
def survey_details(request, id=None):
context = {}
surveys = Survey.objects.get(id=id)
context['survey'] = survey
return render(request, 'surveydetails.html', context)
feedback.urls.py
path('details/<int:id>', views.survey_details, name="surveydetails"),
surveys.html
{% extends 'main.html' %}
{% block content%}
<h1>Surveys</h1>
<h2>list of {{title}} </h2>
{% if surveys %}
<ul>
{% for survey in surveys %}
<li>
{{ survey.title }}
</li>
{% endfor %}
</ul>
{% else %}
<p>There are no surveys.</p>
{% endif %}
{% endblock %}
surveydetails.html
{% extends 'main.html' %}
{% block content%}
<h1>Surveys</h1>
<h2>Detail page</h2>
<h3>{{question.title}}</h3>
<p>Details page of {{question.title}}</p>
{% endblock %}
Here you are not passing the survey id.
{% for survey in surveys %}
<li>
{{ survey.title }}
</li>
{% endfor %}
I have created a very simple login form with flask
email = StringField('E-Mail:', validators=[validators.DataRequired(message='E-mail needed.'), validators.email(u'Provide e-mail.')])
password = StringField('Password:', [validators.required(u'Password can't be empty.')])
And the macro which will create the form inside the template:
{% macro render_field(field) %}
<fieldset>
<div class="form-group">
{{ field(**kwargs) | safe }}
</div>
</fieldset>
{% endmacro %}
As you can see it is very simple form. In the flask tutorial it was showing validation erors for individual fields. But I just want to show them all at once on the top of the form.
Here is my template for that:
<div class="panel-body">
{% if loginForm.errors %}
<div class="alert alert-danger">
<ul>
{% for error in loginForm.errors %}
<li>{{ loginForm.errors[error] }}</li>
{% endfor %}
</ul>
</div>
{% endif %}
<form role="form" method="post" action="{{ url_for('login') }}">
{% from "_formhelper.html" import render_field %}
<fieldset>
{{ render_field(loginForm.email, class="form-control", placeholder="E-Mail") }}
{{ render_field(loginForm.password, class="form-control", placeholder="Password") }}
<button class="btn btn-lg btn-success btn-block">Login</button>
</fieldset>
</form>
</div>
As you can see, i placed my error section on the top of the form. But when
I post empty form, it shows the error messages like this:
['Password can't be empty'] instead of Password can't be empty
Why does it append square brackets and single quotas, start and end of the message? I don't know.
I know that this is an old question but if anyone else has this problem you can fix it by adding a for loop for the messages, something like this:
{% with messages = get_flashed_messages() %}
{% if messages %}
{% for message in messages %}
<div class="alert alert-warning my-5">
{{ message }}
</div>
{% endfor %}
{% endif %}
{% endwith %}
The django contrib comments form i'm using:
{% get_comment_form for post as form %}
<form action="{% comment_form_target %}" method="post">{% csrf_token %}
{% if next %}
<div><input type="hidden" name="next" value="{{ next }}" /></div>
{% endif %}
{% for field in form %}
{% if field.is_hidden %}
<div>{{ field }}</div>
{% else %}
{% if field.name == 'comment' %}
{% if field.errors %}{{ field.errors }}{% endif %}
<p
{% if field.errors %} class="error"{% endif %}
{% ifequal field.name "honeypot" %} style="display:none;"{% endifequal %}>
{{ field.label_tag }} {{ field }}
</p>
{% endif %}
{% endif %}
{% endfor %}
<p class="submit">
<input type="submit" name="post" class="submit-post" value="{% trans "Post" %}" />
</p>
</form>
After submitting the form, it redirects to http://127.0.0.1:8000/comments/posted/?c=..
That means it calls the template django/contrib/comments/templates/comments/posted.html
The content of django/contrib/comments/templates/comments/posted.html:
{% extends "comments/base.html" %}
{% load i18n %}
{% block title %}{% trans "Thanks for commenting" %}.{% endblock %}
{% block content %}
<h1>{% trans "Thank you for your comment" %}.</h1>
{% endblock %}
That doesn't extends my project's base.html.
I need to customize/override that template so that it extends my project's base.html. How can i do that?
If i can't do that, then if i upload my django web project on server, then how would i edit the content of django/contrib/comments/templates/comments/posted.html so that it looks like that:
{% extends "path/to/myproject/templates/base.html" %}
{% load i18n %}
{% block title %}{% trans "Thanks for commenting" %}.{% endblock %}
{% block content %}
<h1>{% trans "Thank you for your comment" %}.</h1>
{% endblock %}
On local pc, for this time i changed/edited the content of django/contrib/comments/templates/comments/posted.html hard-coded to extends my project base.html.
Can anyone give some idea to solve this? I have searched a lot to solve this.
Just override it in your project's "templates" directory:
<project_root>/templates/comments/posted.html
It doesn't seem to be well documented in either the comments app or Django's general template documentation, but it works the same as overriding admin templates (which is documented).
i'm using django-haystack with simple engine, the search is fine, but the pagination is not working. This is the code of my search results template
{% if query %}
<br>
<div id="contenido_pagina">
{% for result in page.object_list %}
{% if result.object.get_model == '[Video] ' %}
{% if result.object.publicar %}
<div class="salida_search">
{{result.object.get_model}}{{result.object.nombre}}<br>
<div class="resumen_search">
{{result.object.sinopsis|safe|truncatewords:"30"}}
</div>
<div class="link_search">
{{result.object.anio}}
</div>
</div>
{% endif %}
{% else %}
<div class="salida_search">
{{result.object.get_model}}{{result.object.titulo}}<br>
<div class="resumen_search">
{% if result.object.contenido %}
{{result.object.contenido|safe|truncatewords:"30"}}
{% else %}
{{result.object.sinopsis|safe|truncatewords:"30"}}
{% endif %}
</div>
<div class="link_search">
{{result.object.fecha|date:"d M Y"}}
</div>
</div>
{% endif %}
{% empty %}
<div>La busqueda <span class="highlighted">{{query}}</span> no obtuvo ningun resultado</div>
{% endfor %}
{% if page.has_previous or page.has_next %}
<div>
{% if page.has_previous %}{% endif %}« Anterior{% if page.has_previous %}{% endif %}
|
{% if page.has_next %}{% endif %}Siguiente »{% if page.has_next %}{% endif %}
</div>
{% endif %}
</div>
<br>
{% else %}
{# Show some example queries to run, maybe query syntax, something else? #}
{% endif %}
when i go to the next page i see the same objects that first page. What i am doing wrong??
I had this issue as well. From debugging the code it looks like it's an issue with the paginator and the searchqueryset. Unfortunately i didn't have more time to devote to it and ended up moving on to whoosh for development environment.
Just encountered this. Seems as though it's a known limitation of the simple backend.

I am trying to implement a comment section on my app that keeps track of bookmarks.
This is the output that I got when I ran my local host server. It is not what I expected and I can't find out what's wrong. I expected there to be a comment form, a number for the comment count, and a comment list. But the webpage just rendered my code.
This is the code
{% extends "base.html" %}
{% load comments %}
{% block title %}Bookmark:
{{ shared_bookmark.bookmark.title|escape }}{% endblock %}
{% block head %}
<h2> Comments</h2>
{% get_comment_count for bookmarks.sharedbookmark
shared_bookmark.id as comment_count %}
{% get_comment_list for bookmarks.sharedbookmark
shared_bookmark.id as comment_list %}
{% for comment in comment_list %}
<div class="comment">
<p><b>{{ comment.user.username }}</b> said:</p>
{{ comment.comment|escape|urlizetrunc:40|linebreaks }}
</div>
{% endfor %}
<p>Number of comments: {{ comment_count }}</p>
{% comment_form for bookmarks.sharedbookmark
shared_bookmark.id %}
{% endblock %}
Thanks for your help!
