I'm creating an inline_form ( inside the data folder and  inside the view folder)​, and the variable i'm passing are strings that i get from different .py file inside the plugin such as the payment_provider.py files or a constant.py.

Hello Hippolyte,

Could you elaborate on which variable and inline forms you are discussing?

You may want to do something like in payment_stripe​ where a serialized dict is set as attribute of a div​ node in Stripe's inline form.
