Form inputs don't create record - ruby-on-rails

Question

I am using paperclip and dropbox for images.
I am not sure why I am getting this. Some of the solutions i tried for resolving the sqlite3 busy exception error didn't work.
But I also suspect my parameters somehow aren't correct...
the controller specifies i need a character object, but the parameters don't seem to have that. I know i use a file attachment called :image, but paperclip, imagemagick, and dropbox are supposed to handle the creation of the image attributes once the image gets uploaded and the form is submitted.
This is the error I get in my browser.
Form:
= form_for(#character, :html => { :multipart => true }) do |f|
- if #character.errors.any?
#error_explanation
%h2= "#{pluralize(#character.errors.count, "error")} prohibited this character from being saved:"
%ul
- #character.errors.full_messages.each do |msg|
%li= msg
#stripe_error.alert.alert-danger{ :style => "display:none" }
%noscript JavaScript is not enabled and is required for this form. First enable it in your web browser settings.
.form-group
= f.label :name
= f.text_field :name
.form-group
= f.label :image
= f.file_field :image
.action
= f.submit
Controller:
def create
#character = Character.new(character_params)
respond_to do |format|
if #character.save
format.html { redirect_to #character, notice: 'Character was successfully created.' }
format.json { render action: 'show', status: :created, location: #character }
else
format.html { render action: 'new' }
format.json { render json: #character.errors, status: :unprocessable_entity }
end
end
end
...
private
# Use callbacks to share common setup or constraints between actions.
def set_character
#character = Character.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def character_params
params.require(:character).permit(:name, :image)
end
end
