Steps for a successful symfony living part 1

ktolis — Wed, 14 May 2008 22:05:18 +0000

Suppose you have a mysql db somewhere. Lets make a very quick CRUD. As fast as possible ..

Requirements:

1) a glass of water,
2) a mysql db
3) the symfony sandbox

Here we go:

Step 1: edit config/databases.yml and use these as last lines:

param:
dsn: mysql://<username>:<password>@<host>/<database_name>

Step 2: edit config/propel.ini to set up propel properly:

propel.database = mysql
propel.database.createUrl = mysql://login:passwd@localhost
propel.database.url = mysql://login:passwd@localhost/database
propel.mysql.tableType = InnoDB

setting up is done now lets get to the fun part

Step 3: we create the model from the mysql db, type at your cli:

symfony propel-build-schema

you should get some echo like:

Generating XML from Creole connection !

and at the end :

[propel-creole-transform] Propel – CreoleToXMLSchema finished

BUILD FINISHED

Total time: 1.1212 second

>> schema putting /var/www/localhost/htdocs/estate/config/schema.yml

>> file- /var/www/localhost/htdocs/estate/config/schema.xml

which indicates the success of the command. You now just created the schema of the db as a yml.

Step 4: now that we got the mysql model lets create the propel model by typing in your cli:

symfony propel-build-model

which will be used from now on throughout symfony.

You are actually done here. You can start building your applications now based on the work so far. So you should start with a backend and finish off with a frontend.

Lets start the backend:

Step 1: type at the cli:

symfony init-app backend

to create the backend application

Step 2: type at the cli:

symfony propel-generate-crud backend images Image

to create the CRUD interface for the Image table and it will appear in the backend application as “images”

You are done for now. You can check out the CRUD at your address:

http://<server_address>/myfolder/web/backend_dev.php/images/list

You can now go on and create simple CRUD interfaces for all your tables by this.

Final Step:

Drink the glass of water. You are done now.

Η ανανεωμένη έκδοση του προηγούμενου script. Η ανανέωση του status δεν γίνεται πλέον χειρονακτικά αλλά κάθε 30″ αυτόματα.

set old_title to " " set new_title to " " repeat delay 30 tell application "Cog" set this_title to the title of the currententry end tell set new_title to this_title if new_title is not equal to old_title then set old_title to new_title tell application "Adium" -- set the status message of the account "****@gmail.com" to this_title set the status message of accounts to this_title end tell end if end repeat
Καλού κακού την postάρισα και στο forum του Cog.

Cog + Adium + status

Το Adium υποστηρίζει εγγενώς την επιλογή να αναφέρει στην τρέχουσα κατάσταση χρήστη το κομμάτι που παίζει το iTunes. Την ίδια συμπεριφορά θέλω να αναπαράγω και με το Cog. Η λύση που βρήκα προς το παρόν είναι μέσω AppleScript ως εξής:
tell application "Cog" set this_title to the title of the currententry end tell tell application "Adium" -- set the status message of the account "youraccounthere" to this_title set the status message of accounts to this_title end tellΚαλού κακού ποστάρισα τον κώδικα και στο φόρουμ της εφαρμογής μπας και το συνεχίσει κανείς μέχρι να ασχοληθώ με το πως μπορώ να καλώ το script αυτό κάθε Χ χρονικό διάστημα ή όταν αλλάζει το κομμάτι που παίζει το Cog. Η λύση που σκεφτόμουν ήταν μέσω Growl αλλά δεν βρήκα το Growl να υποστηρίζει την εκτέλεση AppleScripts ως εναλλακτική η έστω ως συμπληρωματική μέθοδο υποστήριξης events.

Using Natural Selection to Investigate Software Complexities

Acovea Overview
ACOVEA (Analysis of Compiler Options via Evolutionary Algorithm) implements a
genetic algorithm to find the “best” options for compiling programs with the GNU
Compiler Collection (GCC) C and C compilers. “Best”, in this context, is defined
as those options that produce the fastest executable program from a given source
code. Acovea is a C framework that can be extended to test other programming
languages and non-GCC compilers.

I envision Acovea as an optimization tool, similar in purpose to profiling.
Traditional function-level profiling identifies the algorithms most influential
in a program’s performance; Acovea is then applied to those algorithms to find
the compiler flags and options that generate the fastest code. Acovea is also
useful for testing combinations of flags for pessimistic interactions, and for
testing the reliability of the compiler.

This article describes the application of Acovea to the analysis of the GNU C
compiler optimization flags; details about the underlying genetic algorithm can
be found in the companion article,??? A Description of
the Evolutionary Algorithm.
