I'm trying to add the user id to 2 columns in the db after a user successfully submits a form. The commands run fine in the console but wont work in the controller. I haven't added info to the db straight from the controller before so I'm thinking that I'm doing something wrong.
Here is the create method
def create
#game = Game.friendly.find(params[:game_id])
#game_category = Game.friendly.find(#game.id).game_categories.new(game_category_params)
if current_user.mod_of_game? params[:game_id] && #game_category.save
Game.find(#game.id).game_categories.find(game_category.id).update(submitted_by: current_user.id)
Game.find(#game.id).game_categories.find(game_category.id).update(approved_by: current_user.id)
flash[:info] = "Game category added succesfully!"
redirect_to #game
else
render 'new'
end
end
These 2 lines are supposed to add the user id to the submitted_by and approved_by columns but they don't. I don't get any error messages, they simply just don't add anything to those columns
Game.find(#game.id).game_categories.find(game_category.id).update(submitted_by: current_user.id)
Game.find(#game.id).game_categories.find(game_category.id).update(approved_by: current_user.id)
If I replace the lines with coding that works in the console to see if its a variable or something thats not right it still doesn't work
Game.find(12).game_categories.find(55).update(submitted_by: 1)
Game.find(12).game_categories.find(55).update(approved_by: 1)
I'm building an app to learn rails and I guess this is something I just don't know.
Can anyone enlighten me on what I'm doing wrong?
Update:
Ok it is now giving me an error - Couldn't find GameCategory without an ID
So the #game_category.id isn't working?
It is a small typo in your query you missed #.
Game.find(#game.id).game_categories.find(#game_category.id).update(submitted_by: current_user.id)
After playing around tweaking it here and there it turns out to be this line
if current_user.mod_of_game? params[:game_id] && #game_category.save
when changed to this it works
if #game_category.save && current_user.mod_of_game? #game

I have a create method in Rails where I am trying to create multiple objects in a while loop. For some reason it doesn't seem to be hitting the while loop so no objects are being created. The code is below:
def create
#user = User.find(params[:participant][:user_id])
#activity = Activity.find(params[:activity_id])
weeks = #activity.weeks
i = 1
while i <= weeks do
puts "Test"
participant = Participant.new
participant.user_id = #user.id
participant.activity_id = #activity.id
participant.attended = false
participant.paid = false
participant.week = i
participant.save
i = i+1
end
redirect_to user_activities_path(#user, :id => #activity.id)
end
The form I am using to submit is working fine as I can see from the console, and the redirect_to method at the end is working, so it just seems to be missing the loop. If it helps, the value of weeks is 10. Any help would be greatly appreciated.
If multiple Test have been output, try participant.save!, i think the participant save might fail, like some column not valid, so no objects are being created.
Please check if activity record is get fetched. I think your 3rd statement should be as follow.
#activity = Activity.find(params[:participant][:activity_id])
I need to modify the issue's start_date and due_date some how,
But I haven't used Rails before, so I don't know how the it run in server,
And I need to implement it in a short time.
So I add these code in the controller,
def date
issue = Issue.find(params[:id])
issue.start_date = params[:start_date]
issue.due_date = params[:due_date]
ntc_str = "Fail to save!" + params[:id]
if issue.save
ntc_str = 'Issue saved!'
end
flash[:notice] = ntc_str;
redirect_to :controller => 'gantts', :action => 'show', :project_id => params[:p_id]
end
It runs when I access it by myself
It always failed and the "ntc_str" always is "Fail to save!" if I use javascript to access it.
For example:
It runs when I input the url "http://xxx.xxx.xxx.xxx/date?id=6&project_id=test&start_date=2016-06-08&due_date=2016-06-30" by hands,
But it failed when I use javascript "window.location.href='/date?id=6&project_id=test&start_date=2016-06-08&due_date=2016-06-30'"
It runs when I input the params in the form I create and click to submit it,
But it failed when I use javascript "document.getElementById('start_date').value = '2016-06-30'; /..../ $('#test-form').submit()"
Could you tell me why it always fails and how can I use the issue model? I have be crazy now.
It would be useful, if you provide some logs with each cases you try.
Also, you can see what goes wrong with issue, when you try to save it, with:
if issue.save
ntc_str = 'Issue saved!'
else
Rails.logger.error(issue.errors.full_messages)
end
I'm trying to delete a record by passing id of that record. The code looks like this:
def destroy_catalogue_entry
#catalogue_entry = CatalogueEntry.find(params[:catalogue_entry_id])
if #catalogue_entry.destroy
flash[:success] = 'Catalogue entry deleted successfully.'
else
flash[:error] = 'Failed...'
end
end
I'm getting an interesting error. When my function destroy_catalogue_entry is called it shows:
Couldn't find CatalogueEntry with 'id'=16
but as I comment If condition section and render #catalogue_entry as json, the output is printed successfully. So how is it possible? Am I making some silly mistake or is there logical reason. Please enlighten me.
Solved! All I did is this:
def destroy_catalogue_entry
#catalogue_entry = CatalogueEntry.find(params[:catalogue_entry_id])
if #catalogue_entry.destroy
flash[:success] = 'Catalogue entry deleted Successfully'
redirect_to action: :view_catalogue_entries, dc_id: #catalogue_entry.dc_id
else
flash[:success] = 'Failed...'
end
end
When I notice the console, the record was getting deleted successfully but after that there was a SELECT query for the same record, that is why it was throwing the error Couldn't find CatalogueEntry with 'id'=16. As I redirected it, the problem was solved.
I think destroy method is returning an object. In ruby anything other than false or null will be taken to true in if statement. You can do puts on destroy method and see what its returning.
i presume your,
#catalogue_entry = CatalogueEntry.find(params[:catalogue_entry_id])
is returning that error because it cant find CatalogueEntry with id 6, make sure you have CatalogueEntry with that id.
I'm kinda new to coding on rails. It would be great if you could help me out with what I think might be noob question.Here's my code:
def create
#project = Project.new(params[:project])
if #project.save
redirect_to new_project_path
end
student=#project.student_str.split(";")
#users = User.where(:code => student)
#users.each do |c|
puts c.email
end
#users.each do |c|
puts "I'm here"
c.projects = "#{c.projects};#{#project.id}"
end
end
So, in the create method, Each time a new project is created a string called student_str is stored where the ID number of each student is seperated by a ";". I split that string to an array using the split function to get an array of student ID's. I have the puts c.email and puts "I'm here" to make sure the loops are working fine. I get the proper outputs on terminal.
The problem here is the
c.projects = "#{c.projects};#{#project.id}"
That simply does not seem to be working.
My model is not updated when this line is executed. I get no errors though.
Can you tell me what I might have to do to fix this?
thanks!
You have to call c.save after you updated the projects attribute. Otherwise the object is updated but not the database so the next time you load it the changes are gone.
Something really weird is happening and I am not sure how to fix it.
I have two classes on my DB. Projects and timelogs.
On my index method for the Projects controller, I am listing a list of projects and I also want to list the last date where any log was entered for that project.
When I run the code below, I get the following error.
No route matches {:action=>"show", :controller=>"projects", :id=>#<Project id: nil, name: "Project A", user_id: 1, created_at: nil, updated_at: nil>}
If I comment the "select" line and uncomment the line above (with Project.all), everything works perfectly.
Any idea why this could be happening?
def index
##projects = Project.all
#projects = Project.select("julianday(Date('now')) - julianday(log.timeofevent) as diff, *").joins("left outer join timelogs log on projects.id = log.project_id").group("projects.id").order("log.timeofevent asc")
respond_to do |format|
format.html # index.html.erb
format.json { render json: #projects }
end
end
Most likely this is being caused because in the view your code is attempting to create links that will show each project. This might look like this:
link_to 'Show', project
Or maybe like this:
link_to 'Show', project_path(project)
Something in your query is returning rows with no projects.id (as you can see in the error, the id is nil). I suspect your error is the group function, that needs an aggregate function so it definitely seems wrong, I'm not sure immediately why it would be causing a null project.id. Did you mean to use order?

I just realized that you're probably using it to get rid of duplicates. So anyway, back to where everyone else was then I think - more info needed :)
thanks a lot for the answers. You were right on. Indeed, the issue was when the view tried to generate a link and it was missing things like the ID.
I thought that this would work:
#projects = Project.select("julianday(Date('now')) - julianday(log.timeofevent) as diff, *").joins("left outer join timelogs log on projects.id = log.project_id").group("projects.id").order("log.timeofevent asc")
But, apparently "(star)" alone won't work. I had to replace it to "projects.(star)"
So, the resulting fixed code (works fine) is:
#projects = Project.select("julianday(Date('now')) - julianday(log.timeofevent) as diff, projects.*").joins("left outer join timelogs log on projects.id = log.project_id").group("projects.id").order("log.timeofevent asc")
