问题 I am trying to iterate through form.fields in a template and for: {% for field in form.fields %} {{ field }}, {% endfor %} I am getting a list of the field names ("name, description...") instead of the html code that is rendered when using the following: {{ form.name }}, {{ form.description }} (the output in this case is: <input id="id_name" type="text" name="name" maxlength="200" /><input id="id_description"....

问题 One of the ways to limit objects is to add a limitation to a function like this def ten_objects(): obj = Model.objects.all()[0:10] # limit to 10 return {'objects': obj} However how do you achieve this inside a template rather than inside a view?

Via the template. for example the following code will loop through all objects.... <ul> {% for new in

问题 I have a workflow for a model in the Django admin that is very similar to the users' workflow. First, I have a form with basic fields and then, a second form with the rest of the data.

问题 I have a very basic template (basic_template.html), and want to fill in the with data formatted using another partial template.

问题 I am using Django for development, retrieving some text containing a newline character from the database. However, when I render it to a template using a template tag it doesn't show the newline character. What is the problem? 回答1: You have to remember that your templates are producing HTML.
