Hi,
I’m relatively new to Phoenix and haven’t come across the proper way to use Phoenix form helpers to create fields that exist in a Postresql JSONB column.
In my table, I have a column called “details” that I want to store a serialized map of key-value pairs, like:
{"age": 22, "home_town": "Washington, DC"}
According to these docs, I should be doing something like:
<%= form_for @changeset, Routes.user_path(@conn, :create), fn f -> %>
<%= text_input f, :details %>
<% end %>
How do I adjust the text_input f, :details (maybe like text_input f, :details[age] to specify an input that exists within the details map, that would produce some markup like:
<input type="text" name="user[details][age]" class="form-control border"></input>
I thought something like the “fields_for” helper would achieve this, but it seems to only be used to enter fields for associated resources like a has_many/belongs_to relationship:
<%= form_for @changeset, Routes.user_path(@conn, :create), fn f -> %>
<%= text_input f, :name %>
<%= inputs_for f, :permalink, fn fp -> %>
<%= text_input fp, :url %>
<% end %>
<% end %>
How should I use the Phoenix form helpers to achieve this? Thanks for any help!
