Failed to load resource: the server responded with a status of 400 (Bad Request)?

Question

Ruby on Rails

When I try to create an entry, I get the following error:

Started POST "/spr_type_events" for 127.0.0.1 at 2018-07-02 14:16:20 +0500
Processing by SprTypeEventsController#create as JSON
  Parameters: {"spr_type_event"=>{}}
Completed 400 Bad Request in 1ms

ActionController::ParameterMissing (param is missing or the value is empty: spr_type_event):

app/controllers/spr_type_events_controller.rb:43:in `spr_type_events_params'
app/controllers/spr_type_events_controller.rb:15:in `create'

Answer 1

It's written in the log:

Parameters: {"spr_type_event"=>{}}

That is, the form attributes required to create a SprTypeEvent are missing.

How can you get rid of it?

Submit the required attributes.
In line

params.require(:spr_type_event).permit!

when trying to extract attributes from :spr_type_event there was a bummer. :-)
There is also a typo in the create method:
"erros"
