Hi, I'm not an expert, but I had also plenty of problems with Rails db connections in the beginning, almost every time another solution solved my problems.
First: if you try "rails -v" or "rails --version" you have to see some version number. It is important, if you cannot (like I did not), than reinstall is the solution. (I assumed that you use Unix based system) It is also useful, because of (as I know) the "-d ..." syntax changed, In earlier versions it was "-d=..." (or like this but Im not sure about it, it is unnecessary to know, but it can be problem, if you do not update! ;)) Next problem can be with db connection: 1. connection in .yaml, (now it seems ok); 2. name+pw (it seems ok); 3. is the db server running? If you can change the db manually, than the .yaml have to has the problem - also check the port, socket, other infos, it differs for different dbs! If you cannot, than first fix that, than dont forget the .yaml! For me it helped a lot not to change the basic database setup, so just used it without "-d ..." and later, when understand a bit more, I could figure it out. This blog app just confused me like hell, but I found a very useful staff from Pragprog: http://www.pragprog.com/titles/rails4/agile-web-development-with-rails good luck, gezope On aug. 19, 17:16, "Ivan K." <[email protected]> wrote: > Hello; > > I have begun the "Getting Started with Rails" guide > athttp://guides.rubyonrails.org/getting_started.html > which is supposed to create a simple blog. > > I execute the command "rails blog -d postgresql" without incident. > > I am having trouble with the next command in the tutorial: > "rake db:create". > > The first time, I received the messages: > > FATAL: role "blog" does not exist > ... > Couldn't create database for {"encoding"=>"unicode", > "username"=>"blog", > "adapter"=>"postgresql", "database"=>"blog_development", > "pool"=>5, "password"=>"xxxxyyy"} > > So I created the postgres account blog and gave that account the > ability to create databases and users.
