How to store boolean value in jsonb column - ruby-on-rails

Question

I'm getting a checkbox value from my form like this
<%= f.label 'Most Popular', class: "form-label" %>
<%= check_box_tag "price_template[preferences][pcb_budget_options][][most_popular]",
true,
f.object.preferences.dig("pcb_budget_options", index, "most_popular") %>
And the params I am permitting is like this
params.require(:price_template).permit(:currency_id,
:program_id,
:active,
:default,
country_ids: [],
preferences: [budget_options: [:amount, :most_popular, :text],
pcb_budget_options: [:amount, :most_popular]])
and it stored in DB like this
{
"budget_options"=>[
{"amount"=>"1.0", "text"=>"budget options"},
{"amount"=>"2.0", "most_popular"=>"true", "text"=>"budget options"},
{"amount"=>"3.0", "text"=>"budget options"}
],
"pcb_budget_options"=>[
{"amount"=>"1.0"},
{"amount"=>"0.0"},
{"amount"=>"-1.0", "most_popular"=>"true"}
]
}
but the most_popular value is stored here is in string format but I want to store it as a boolean.

It's not possible in jsonb it will be always save as a "string" in the DB.
You can create your own serializer to parse the jsonb as you want or if only the boolean part matter for you, you can create a method in your model like this
class Mymodel
def budget_most_popular
ActiveRecord::Type::Boolean.new.cast(preferences["budget_options"]["most_popular"])
end
def pcb_budget_most_popular
ActiveRecord::Type::Boolean.new.cast(preferences["pcb_budget_options"]["most_popular"])
end
end
So anywhere in your code you can get a real boolean value by calling this method.
Imagine you have the following record
$> MyModel.first
<MyModel:0x029I23EZ
id: 1,
name: "foo",
preferences: {
"budget_options" =>
[
{ "amount"=>"10", "most_popular"=>"true", "text"=>"" },
{"amount"=>"0.0", "text"=>""}, {"amount"=>"0.0", "text"=>""}
],
"pcb_budget_options"=>
[
{"amount"=>"20", "most_popular"=>"false"}, {"amount"=>"0.0"},
{"amount"=>"0.0"}
]
}
...
And somewhere in your code you need to check if budget_option is most_popular
class MyModelController
def show
#mymodel = MyModel.first
if #mymodel.budget_most_popular
render "template/most_popular"
else
render "template/less_popular"
end
end
end
Since in our last record budget_options as most_popular set as 'true' our model method budget_most_popular will cast this 'true'to return a boolean true so our show will render the most_popular template
