Run more examples¶
Reahl comes with a number of examples. These are not self-explanatory – they are referred to all over in the rest of the tutorial to illustrate what is explained there.
Here is a cheat sheet when you come across an example in and you wonder how to run it.
Listing and checking out examples¶
To list all the examples that come with Reahl:
reahl listexamples
The list of example names this outputs are referred to all over in our documentation.
To get an example, run (e.g.):
reahl example tutorial.hello
This will create a directory “hello” in your current location containing the example.
Running examples¶
After first checking out an example, do the following before trying to run it:
Go to the checked out example:
cd helloPrepare the example for development:
reahl setup -- develop -N
Create a database:
reahl createdbuser etc reahl createdb etc reahl createdbtables etc
Once that is done, run the example:
reahl serve etc
Helpful hints¶
Each examples creates a sqlite database file in the root the example’s directory with a name derived from its reahlsystem.root_egg configuration setting. The latter defaults to the name of the directory in which the example resides.
To see the current configuration of an example (and which file to set it in) run:
reahl listconfig -f -v
You can drop the database for an example with:
reahl dropdb etc
To remove a previous example from development, run:
reahl setup -- develop -N --uninstall
