I have a two-dimension array in my django app which I need to pass to html template.
How I can make HTML handle two-dimensional array?
{% block content %}
<h2>Survey</h2>
<form>
{% for q in question %}
<p>{{q[0]}}</p>
<p>{{q[1]}}</p>
{% endfor %}
<input type="submit" value="submit">
</form>
{% endblock %}
I got error:
Could not parse the remainder: '[0]' from 'q[0]'
{% block content %}
<h2>Survey</h2>
<form>
{% for q in question %}
<p>{{q.0}}</p>
<p>{{q.1}}</p>
{% endfor %}
<input type="submit" value="submit">
</form>
{% endblock %}
Django just doesn't have a pre-setup way for passing multi-dimensional arrays to templates.
The best work-around is to separate the columns out manually like so... ("i" corresponds to each row in final output)
data = {}
for i, question_answer in enumerate(question_answer_pairs):
data[i]= {
'question':question_answer.question,
'answer':question_answer.answer
}
return render(request, 'survey.html', data)
Then in your template
{% block content %}
<h2>Survey</h2>
<form>
{% for key,value in data.items %}
<p>{{value.question}}</p>
<p>{{value.answer}}</p>
{% endfor %}
<input type="submit" value="submit">
</form>
{% endblock %}
