[英]ActionController::UnknownFormat error
我想從控制器中的方法調用JavaScript函數,該函數以方法create.js.erb的名稱寫入文件中,但出現錯誤ActionController :: UnknownFormat。我不知道這是什么問題?
app / views / favorite_places / create.js.erb
function my_function()
{
swal("Place is not saved in google maps!", "Please move the marker to the desired location and add its name");
}
應用程序/控制器/ favorite_places_controler
def create
#Checks if the current user have this favorite place already ,it renders Favorite Place already exists
if current_user.favorite_places.include?(FavoritePlace.find_by(:name => favorite_place_params[:name]))
id=FavoritePlace.find_by(:name => favorite_place_params[:name]).id
redirect_to favorite_places_path , notice: 'Favorite place already exists'
else
#Checks if the favorite Place exists in the database it finds the place puts it in the variable favorite place
if FavoritePlace.exists?(:name => favorite_place_params[:name])
@favorite_place = FavoritePlace.find_by(:name => favorite_place_params[:name])
#Or it will create a new one with the allowed parameters only.
else
@favorite_place = FavoritePlace.new(favorite_place_params)
@favorite_place.save
end
id=@favorite_place.id
#It assigns the favorite place to the user.
UserFavoritePlace.add_favorite_place(current_user,@favorite_place)
redirect_to favorite_places_path , notice: 'Favorite place was successfully added.'
respond_to do |format|
format.js { render :js => "my_function();" }
end
end
end
您在react_to塊之前有一個redirect_to,這是錯誤的-redirect_to應該位於response_to塊內的format.html塊中。
您未知的格式錯誤可能是由於控制器嘗試處理和html請求而引起的,而您沒有在respond_to塊內處理該請求。 嘗試改變這個
redirect_to favorite_places_path , notice: 'Favorite place was successfully added.'
respond_to do |format|
format.js { render :js => "my_function();" }
end
對此
respond_to do |format|
format.html { redirect_to favorite_places_path , notice: 'Favorite place was successfully added.' }
format.js { render :js => "my_function();" }
end
