问题 I have a rails 4 app using boostrap-sass and chartkick charts. Everything works great local but when I tried to push to heroku I got errors that searching revealed were probably due to js problems.

问题 I'm writing a Python app to deploy on Heroku. Per Heroku's guide, I need to list package requirements in a Pip requirements.txt file. The guide instructs me to install the packages locally, then run pip freeze > requirements.txt to write the frozen requirements file.

However, how can I query and access my postgres database that is up on heroku? 回答1: You can run heroku run rails c --app <appname> .

问题 I didn't have trouble on previous code pushed to Heroku, but this last push has messed up. The only thing that has changed is instead of looping through each student , it's now looping through each user . Background The code works locally, but not on Heroku. The page that is raising an error on Heroku is a list (index) of all the students. What the code is doing is looping through all Users that have a profile_type = "Student" . For some reason it's trying to access the polymorphic

问题 I've successfully made a test chat app and I've gotten a node js server with socket.io running on heroku. On my local computer I have to specify the port number of localhost on the client side to the port that the server has set up. However, when I run my server code on heroku. Removing the server I'm using the process.env.PORT variable since heroku sets that up: var port = process.env.PORT || 3000; http.listen(port, function(){ console.log('listening on *:' + port); }); Naturally I find the

问题 Originally I couldn't push my rails 4 app to heroku because my database was sqlite, and so now I have been trying to install the Postgresql gem ('pg') but I am not having any luck.
