Issue
I tried:
list1 = [{"username": "abhi", "pass": 2087}]
return render_template("file_output.html", list1=list1)
In the template:
<table border=2>
<tr>
<td>
Key
</td>
<td>
Value
</td>
</tr>
{% for dictionary in list1 %}
{% for key in dictionary %}
<tr>
<td>
<h3>{{ key }}</h3>
</td>
<td>
<h3>{{ dictionary[key] }}</h3>
</td>
</tr>
{% endfor %}
{% endfor %}
</table>
The above code is splitting each element into multiple characters:
[
{
"
u
s
e
r
...
I tested the above nested loop in a simple Python script and it works fine but not in Jinja template.
Solution
Data:
parent_list = [{'A': 'val1', 'B': 'val2'}, {'C': 'val3', 'D': 'val4'}]
in Jinja2 iteration:
{% for dict_item in parent_list %}
{% for key, value in dict_item.items() %}
<h1>Key: {{key}}</h1>
<h2>Value: {{value}}</h2>
{% endfor %}
{% endfor %}
Note:
Make sure you have the list of dict items. If you get UnicodeError
may be the value inside the dict contains unicode format. That issue can be solved in your views.py
.
If the dict is unicode
object, you have to encode into utf-8
.
