Overview
Through padrino-lazy, we can include some common properties shared between the model object used a base model object
Padrino is very good framework, and almost follows the DRY principle (Don’t Repeat Yourself) When we need to have some common properties shared between the model object of our ORM, using the generator padrino-gen, We can only include these properties in each model to generate.
I hope this idea will be included in Padrino Framework.
Principle / Step
- generate a model
- convert the model into base model ( move this model into lib/ folder)
- save config file with model base’s list
- generate a model from base model
- generate a migration file
Usage
Step 1-2-3
1
| $ padrino-lazy base --c config_file --b base_model_name --f field_to_create |
Step 4-5
1
| $ padrino-lazy model --c config_file --b base_model_name --f field_to_create --m model_name |
Install
1
| gem install padrino-lazy --pre |
Example
1
| $ padrino-lazy base --c config --b BaseModel --f "create_at:datetime is_active:boolean" |
now we have
lib/base_model.rb class BaseModel

Known issue
- VERY VERY alpha code !! (thanks to my pig/lazy side
)
- —f options need dobule quote around fields
- —b write in CamelCase
- TESTING only with datamapper and activerecord into linux machine
TODO:
- Test all code !
- Use Padrino::Generators instead of Commander
- Default config file name (very lazy
)
THANK

# Unmount the filesystem and check its' LV
umount /mnt/foo
e2fsck -f /dev/mapper/vg0-foo
# Shrink ext4 and then the LV to the desired size

lvreduce -L 40G /dev/mapper/vg0-foo
# Before continuing, run e2fsck. If it bails because the partition
# is too small, don't panic! The LV can still be extended with
# lvextend until e2fsck succeeds, e.g.:
# lvextend -L +1G /dev/mapper/vg0-foo
e2fsck -f /dev/mapper/vg0-foo
# Resize the filesystem to match the LVs size, check and mount it
resize2fs -p /dev/mapper/vg0-foo
e2fsck -f /dev/mapper/vg0-foo

# Backup file remote/local
# By Carlo Bertini [WaYdotNET]
# il tutto utilizzando rsync senza scomodare subversion
# RSYNC OPTION
# -r => ricorsivo
# -l => copy symlinks as symlinks
# -p => preserve permissions
# -v => verbose
# -u => update, ignorare i file che sono più nuovi nella destinazione
# -a => archive mode
# -z => comprime i file durante l invio
# -h => rendere leggibile l output
# --delete => cancello i file estranei nella destinazione
# il comando si deve chiamare con:
demo="sync_to_waydotnet [up or down] local_folder remote_folder"
# VARIABILI
base="~/backup"
type=$1
local_folder=$2
remote_folder=$base/$3
host="HOST.EXT"
user="user"
if [ $type = "up" ] ; then
echo "UPLOAD $local ==> $remote"
rsync -lrpuazhv --delete -e ssh $local_folder $user@$host:$remote_folder
elif [ $type = "down" ] ; then
