Undefined method? Controller params in Rails 4 -

i getting weirdest error have ever seen, consider next create method:

def create post = post.find_by(id: params[:post_id]) @comment = comment.new(comment_create_params) @comment.post_id = post.id #i know line useless have yet refactor. controller_save(@comment) end

from here have comment_create params private method defined such:

def comment_create_params params.require(:comment).permit(:author, :comment, :parent_id) end

now consider next params passed in:

params => {"author"=>"157685iyutrewe1wq", "comment"=>"14253647turyerwe", "action"=>"create", "controller"=>"api/v1/comments", "post_id"=>"126"}

based on looks correct. running through function should save. till next error:

nomethoderror: undefined method `permit' "14253647turyerwe":string

i have no thought means - think trying treat: "14253647turyerwe" method string? not sure....

params

params.require(:comment).permit(:author, :comment, :parent_id)

this hash inherits comment key, this:

{"comment" => { "id" => "5", "name" => "test" } }

so when utilize require method, you're saying "we need top-level hash key", rails go nested hash & utilize permit method locate other attributes, shown above.

the problem have this:

params => {"author"=>"157685iyutrewe1wq", "comment"=>"14253647turyerwe", "action"=>"create", "controller"=>"api/v1/comments", "post_id"=>"126"}

the problem here you're calling require on comment key; string. prepare this, you'll need this:

def comment_params params.permit(:author, :comment, :action) end

save

something else need consider controller_save method. i've never seen before, , against convention. not problem this, means if team members on app, or want upgrade rails, pain adapt it.

i utilize standard .save method, this:

#app/controllers/comments_controller.rb def create ... @comment.save end
