Some basic documentation can be found here.

Using Polars data in Django template html

lets start with their demo.

df = pl.DataFrame(
  {
    "foo": [1, 2, 3],
    "bar": [6, 7, 8],
  }
)
df.write_json()

'[{"foo":1,"bar":6},{"foo":2,"bar":7},{"foo":3,"bar":8}]'

I pass in the df in the from the df.write_json()

context = {

    'df' : df,
}

But nothing i am trying in Django is working? the json was the only option i see to pass the data.

techinally this is a list of dicts?

<ul>
{% for i in df %}    # tried many option here

    {{ i.foo }}

{% endfor %}
<ul>

i have tried all sorts of things.

for Pandas i would just use df.to_records()

what is best way to get Polars data into a Django template to use in things like tables?

loving polars so far but getting confused by a few things. Like this one.

Thanks!

    df.write_json() will produce a string, so you will enumerate over the characters, you should use .to_dict('records') [pandas-doc]:

    context = {
    'df': df.to_dict('records'),
}

    you’re not writing your html as you should. you need to insert <li> tags

    <ul>
{% for i in df %}    # tried many option here

    <li>{{ i.foo }}</li>

{% endfor %}
<ul>
