I am trying to iterate through a nested hash to access two separate fields. This is what I am trying to do:
- Check to see if
:is_cover_photo
is true
- if
:is_cover_photo
is true then I want to call the update method on @point_of_interest
.
I keep getting an error thrown and cannot figure out how to accomplish this task.
This is error I am getting: "no implicit conversion of Symbol into Integer"
This is in my update
method of point_of_interests_controller
:
def update
@point_of_interest = PointOfInterest.find(params[:id])
if @point_of_interest.update(params[:point_of_interest].permit(:title, :caption, :website, :summary, :latitude, :longitude, :cover_photo, albums_attributes: [:id, :cover_photo, :title, :is_cover_photo]))
params[:point_of_interest][:albums_attributes].each do |key, value|
value.each do |k, v|
if k[:is_cover_photo] && k[:cover_photo].blank?
@point_of_interest.update(:cover_photo => k[:cover_photo])
end
end
end
redirect_to @point_of_interest
else
render 'edit'
end
end
Here are the parameters being passed:
{"utf8"=>"✓",
"_method"=>"patch",
"authenticity_token"=>"XGvgfxFHZKpiE8eGqc+55qOlSSk9LYFGdywWyABezXo=",
"point_of_interest"=>{"title"=>"WolfieOne",
"latitude"=>"33.577836",
"longitude"=>"-85.074692",
"caption"=>"CaptionOne",
"website"=>"google.com",
"summary"=>"This is a test summary.",
"albums_attributes"=>{"0"=>{"title"=>"Album Uno",

@original_filename="Lighthouse.jpg",
@content_type="image/jpeg",
@headers="Content-Disposition: form-data; name=\"point_of_interest[albums_attributes][0][cover_photo]\"; filename=\"Lighthouse.jpg\"\r\nContent-Type: image/jpeg\r\n">,
"is_cover_photo"=>"1",
"id"=>"23"},
"1"=>{"title"=>"Album 2",
"is_cover_photo"=>"0",
"id"=>"24"},
"2"=>{"title"=>"The Best Album Alive",
"is_cover_photo"=>"0",
"id"=>"30"}}},
"commit"=>"Submit Wolfie",
"id"=>"15"}
Any help on this would be greatly appreciated.
Update
This resolved the issue for me:Thanks to Coenwulf
params[:point_of_interest][:albums_attributes].each do |key, value|
if value[:is_cover_photo] && value[:cover_photo].present?
@point_of_interest.update(:cover_photo => value[:cover_photo])
end
end
