Django-easy-pdf, header on every page of the document

由 你说的曾经没有我的故事 提交于 2019-12-06 22:52:33
I am trying to export some data in a PDF file. I am using: Django 1.9.12 django-easy-pdf 0.1.0 Python 2.7 The export works fine and all (no problem with my view) but I am struggling with adding a page header into every page of the document. At this point I can only render it on the first page. I have no such problem with the footer, it renders properly on every page. My template is as follows: {% extends "easy_pdf/base.html" %} {% block extra_style %} <style type="text/css"> @page { size: landscape; margin-left: 1cm; margin-right: 1cm; margin-top: 1.5cm; margin-bottom: 2cm; @frame footer {

Django: How to display Validation errors not specific to a field?

由 烈酒焚心 提交于 2019-12-06 20:37:39
问题 I have errors raised in the form's clean method (not tied to a field). How do I display them in the template? I tried {{ forms.errors }} and {{ form.non_field_errors }} but neither worked. 回答1: According to the docs, they go in a special field ( __all__ ) and should be accessed via the non_field_errors() method. At a guess, I'd say that method returns a sequence. 来源： https://stackoverflow.com/questions/1883469/django-how-to-display-validation-errors-not-specific-to-a-field

Here's my problem: class City(Model): name = StringProperty() class Author(Model): name = StringProperty() city = ReferenceProperty(City) class Post(Model): author = ReferenceProperty(Author) content = StringProperty() The code isn't important... its this django template: {% for post in posts %} <div>{{post.content}}</div> <div>by {{post.author.name}} from {{post.author.city.name}}</div> {% endfor %} Now lets say I get the first 100 posts using Post.all().fetch(limit=100) , and pass this list to the template - what happens? It makes 200 more datastore gets - 100 to get each author, 100 to get

Django Template Not Found

由 隐身守侯 提交于 2019-12-06 19:27:17
问题 I have a Django problem which only occasionally has problems finding Templates. It will be running fine for hours, and then suddenly not be able to serve certain templates. Occasionally the problem will correct itself, but can always be fixed by running touch <template> . My current solution is a cronjob which executes touch <project root> every minute, and that works so long as cron keeps up. However, I want to figure out a proper solution to my problem. Relevant Settings: PROJECT_ROOT = os

Django template variable value to string literal comparison fails

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-06 18:21:56
问题 I have the following code in my template that supposed to compare the value of watchinstance.shift , which can be either "DAY" or "NIGHT", to a literal string "DAY". The comparisson always fails. {% for watchinstance in watchinstance_list %} {% if watchinstance.shift == "DAY" %} <p>shift is DAY</p> {% endif %} {% endfor %} Using ifequal doesn't work either: {% for watchinstance in watchinstance_list %} {% ifequal watchinstance.shift "DAY" %} <p>shift is DAY</p> {% endifequal %} {% endfor %}

Displaying a timedelta object in a django template

由 故事扮演 提交于 2019-12-06 17:16:26
问题 I'm having trouble getting my django template to display a timedelta object consistently. I tried using the time filter in my template, but nothing is displayed when I do this. The timedelta object is shown as follows on the errors page if I use Assert False: time datetime.timedelta(0, 38, 132827) This displays the time difference as: 0:00:38.132827 I would like to only show the hours, minutes, and seconds for each timedelta object. Does anyone have any suggestions on how I can do this? 回答1:

Is it possible to use django's custom template tags to insert code in other blocks in the template?

由 与世无争的帅哥 提交于 2019-12-06 15:57:52
I'm writing a custom template tag that wraps an HTML element with some code to make it editable. This is backed up by some CSS, and JS that takes care of sending the data to the server to save it. This component requires the inclusion of <script type="text/javascript" src="../myscript.js"></script> at the bottom of the page and <link rel="stylesheet" type="text/css" href="../mystyle.css"> at the top. I already have two "js" and "css" template blocks in the page template. My question - is there a way for for the custom template tag to include these scripts once in the relevant page blocks, if
