Hi, gurus!
I am trying to get twoorl to work with erlyweb 7.1.
1. I cannot make the yaws.conf to point to my /usr/local/twoorl/www before I create it. If I do so, yaws -i will have error because there is no such directory exist for now.
2. If I erl and do a erlyweb:create_app("twoorl","/usr/local"). I will get an index.html file which is not about twoorl. The index.html is the same as in the music tutorial. Nothing with twoorl.
So, I did not create the application directory struture and I get into yaws -i.
I did a erlydb:start(mysql,[{hostname,"localhost"},....
Then I did a erlyweb:compile("/usr/local/twoorl",[{erlydb_driver,mysql}]).
Finally, I did a twoorl:start().
I did not find error message.
But when I http://localhost/
It gives me error messages:
ERROR erlang code crashed:

Before all of these, I made connection to mysql.
I download a file called twoorl_server.erl and put in the src directory.
I changed the twoorl_app.hrl and did erlc twoorl.erl
and in the twoorl directory I did a make clean and make. I have executed all sql scripts in imigration directory.
All of these have no error message until I http://localhost with it.
If I go to http://localhost/twoorl, it pop out the twoorl home page. I fill up the user name and email and password, then I click on submit. It went to /home and pop out the above error message.
I had checked into the database. The user really has inserted into the tables.
Thanks a lot! |
