Django template jinja for loop - django

Question

Can someone suggest me how to iterate a dictionary in django template?
dic1={5: ['jaw replacement - 23-Jun-2020 (16:20:09.164240)', 'jaw replacement done - 23-Jun-2020 (16:20:51.158085)', 'jaw replacement done,almost done - 23-Jun-2020 (16:25:40.066955)', 'jaw replacement done,almost done 1 - 23-Jun-2020 (16:27:00.355605)', 'jaw replacement done,almost done 2 - 23-Jun-2020 (16:31:35.111660)']}
this is the context i am passing
i need something like this in template
for i in dic1:
print(i)
list1=dic1[i]
for k in list1:
print(k)
{% for i in notes %}
{% with list1=dic1[i] %}
{{list1}}
{% endwith %}
{% endfor %}
This is not working.

Answer 1

Lets say your data is -
dic1 = {'a': [ [1, 2] ], 'b': [ [3, 4] ],'c':[ [5,6]] }
You can use the data.items() method to get the dictionary elements. Note, in django templates we do NOT put (). Also some users mentioned values[0] does not work, if that is the case then try values.items.
<table>
<tr>
<td>a</td>
<td>b</td>
<td>c</td>
</tr>
{% for key, values in dic1.items %}
<tr>
<td>{{key}}</td>
{% for v in values[0] %}
<td>{{v}}</td>
{% endfor %}
</tr>
{% endfor %}
</table>
I hope It helps you.

Answer 2

In normal Python you would normally access keys and values by using the items() method on a dictionaty.
For example given the dictionary
some_dic = {'1': 'Hello', '2': 'World'}
You should be able to access this by doing the following:
for key, value in some_dic.items():
print(key, value)
You can follow this same principle in Django templates and simply omit the '()' as follows:
{% for key, value in some_dic.items %}
<h1>Key: {{ key }}</h1>
<h1>Value: {{ value }}</h1>
{% endfor %}

Answer 3

you can pass dic1 one directly to the template from view and iterate through dictionary in template \
in view
return render(request, 'template.html',{'dic1':dic1})
#intemplate.html
{% for key, value in dic1 %}
<tr>
<td> Key: {{ key }} </td>
{% for value_in_array in value %}
<td> Value: {{ value }} </td>
{% endfor %}
</tr>
{% endfor %}
