how to use ACL in Symfony2 - symfony

I am trying to use ACL for my project, I have not done it before. I know only the concepts, what it is and why to use it.
I run this command :
$ php app/console init:acl
and I got five tables in my database .
My question is how to use these tables, means how data will be inserted in these tables .
I also have followed steps from here
and still not getting the hang of it , please help me out .

You should'nt use table directly (but you already know), but ACL Entities instead (but it's tricky).
Some people worked on bunbles to simplify those actions. Here is an example on how to use it :
https://github.com/Problematic/ProblematicAclManagerBundle
$comment = new Comment(); // create some entity
$aclManager = $this->get('problematic.acl_manager');
// Adds a permission no matter what other permissions existed before
$aclManager->addObjectPermission($comment, MaskBuilder::MASK_OWNER, $userEntity);
// Replaces all current permissions with this new one
$aclManager->setObjectPermission($comment, MaskBuilder::MASK_OWNER, $userEntity);
$aclManager->revokePermission($comment, MaskBUILDER::MASK_DELETE, $userEntity);
$aclManager->revokeAllObjectPermissions($comment, $userEntity);
You can apply permission on objects or directly on classes (upper level)

Nelmio/Alice 2.x Symfony 3 , Loading Related Fixtures in Different Bundles

If there's already answer to my question then sorry and please point me in the right direction because I can't find anything.
Let's say I have two Bundles. Each bundle has fixures.yml file and loader file.
Loaders and fixtures are working fine when they are not depending on each other.
However when I am referencing fixtureA from fixtureB I get duplicated record in database.
E.g:
user_{1..10}:
email (unique): '<firstName()>+<randomNumber()>#gmail.com'
plainPassword: 'secret'
story_{1..10}:
user: "#user_<current()>"
title: '<word>'
When they are in separated files - duplicated row. When they are in the same file everything is ok.
Why it's being loaded twice?
I even tried this:
$objects = Fixtures::load(__DIR__ . '/fixtures.yml', $manager, ['persist_once'=>true]);
No luck.
Evey time I am trying to use user object in story fixtures alice tries to save it into db again.
Best Regards,
Robert
I did a little research and talked to people - it looks like it's a possible bug. You can learn more here:
Nelmio/Alice 2.x Duplicated Row
Also I would like to share my work around:
I wanted to keep things separated and clean. Instead of keeping all fixtures in one file in one bundle you can move it to App/DataFixtures/ORM directory. However Symfony will not look for fixtures in this directory. You can:
add path to the fixtures in console command:
doctrine:fixtures:load --fixtures=/var/www/story/app/DataFixtures/ORM
create alias for above solution
override DoctrineFixturesBundle - how to do this
I hope this will help if you have similar issue.

Drupal 8: Mismatched entity and/or field definitions

While trying to understand why my view is not displaying, I noticed the following error in the log:
I do not think it is possible to delete the URL alias from Taxonomy terms. At least I cannot find how to do this.
I have, however gone through ALL of my taxonomy terms and removed the value for this field.
I have also done the following with Pathauto:
Also, I have checked the report located at admin/reports/fields and can confirm that there are no entities that use a field called URL alias.
I have gone through each content item and ensured that they have the following setting (anyone know how to do this in bulk?). But still the error remains.
Anyone know then how I can fix this strange error?
Im not entirely sure what this command does, but it fixed the error:
drush updb --entity-updates
Since https://www.drupal.org/node/2554097, the magic in Drupal core that took care of updating entity definitions is gone. drush updb --entiy-updates is an alternative to this but it is not a silver bullet. Instead, it is safer to write database updates.
Taking the screenshot at the top as an example, here is a database update that would delete those two field definitions:
/**
* Fix taxonomy and node field definitions.
*
*/
function mymodule_update_8101() {
$manager = \Drupal::entityDefinitionUpdateManager();
if ($field = $manager->getFieldStorageDefinition('alias', 'node')) {
$manager->uninstallFieldStorageDefinition($field);
}
if ($field = $manager->getFieldStorageDefinition('alias', 'term')) {
$manager->uninstallFieldStorageDefinition($field);
}
}
Have a look at the rest of the available methods at https://www.drupal.org/node/2554097 in order to write database updates for each scenario.
use the entity_update module or the devel_entity_updates module

Can the Path assigned a SQLite DB be an arbitrary value?

In this blog post, some prerequisite code for getting started using SQLite in Windows Store Apps is given, for adding to the OnLaunched method of App.xaml.cs:
// Get a reference to the SQLite database
this.DBPath = Path.Combine(
Windows.Storage.ApplicationData.Current.LocalFolder.Path, "customers.sqlite");
My question is: Can I use any arbitrary value to replace the "customers.sqlite" part, or does it have to match something else in my code, such as the name of my table definition class (in my case "PhotraxCoreData.cs" which, according to Mr. Green's suggestion, I added below a newly-created "Models" folder)?
My understanding is that, once I've got those classes defined (I do), and the code above in App.xaml.cs, along with this there (adapted for my SQLite classes):
using (var db = new SQLite.SQLiteConnection(this.DBPath))
{
// Create the tables if they don't exist
db.CreateTable<PhotraxBaseData>();
db.CreateTable<PhotraxNames>();
db.CreateTable<PhotraxQueries>();
}
...SQLite tables based on those classes I specified will be created, and have the name "customers.sqlite" (provided I don't change it).
So, can I use:
this.DBPath = Path.Combine(
Windows.Storage.ApplicationData.Current.LocalFolder.Path, "platypus.sqlite");
...or must it be something like:
this.DBPath = Path.Combine(
Windows.Storage.ApplicationData.Current.LocalFolder.Path, "PhotraxCoreData.sqlite");
That database name is just a file name.
The directory must be accessible by your app, but the file name can be anything.
AS CL says, the file name can be anything the app has direct access to. Windows Store apps have limited access to the file system, so the sqlite database must be in either the apps install location (read only) or it's app data folder (read write). A common pattern is to ship a seed database in the app package and then copy it from the install location to app data on first use so it can be written to.

Drupal user permissions & odd content types

I have a permissions problem in Drupal. I want users to be able to create a certain node type, but there are two different paths I need to give them permissions for to let them do this. The type is content created by a module called isbn2node, and there are two ways to make content through it, each with different paths:
?=node/add/isbn2node-book
?=node/add/isbn2node_book/isbn2node
One has an underscore and the other one has a hyphen. The first path leads to a form that lets users enter information on a book manually; the second path lets them enter an ISBN, searches for it, and populates the form for them based on the results.
I've changed permissions in the People menu so they can add isbn2node-book content manually using the first path, but there isn't an option to let them use the second method. Aliasing the url so it didn't have node/add in the path didn't work either.
Creating a duplicate content type seems like an ugly solution to this; is there a more elegant way to let users access that second path?
A little code in a custom module using hook_node_access should do it.
$node is either a node object or the machine name of the content type on which to perform the access check (if the node is being created then the $node object is not available so it will be a string instead).
So this should do it:
function MY_MODULE_node_access($node, $op, $account) {
if ($op == 'create') {
$type = $node;
if($type == 'book' && $account->uid) return NODE_ACCESS_ALLOW;
}
}
I figured this out, and the issues I was having were specific to this content type. The ISBN2Node module requires users to have the Administer Nodes permission to use its lookup and bulk import features.
There is some extra code for the module's hook_permission and hook_menu sections submitted as a fix in the module's issues thread.

Using specific drupal-related functions in a non-drupal.php file INSIDE the drupal dir

Good morning all.
I'm having some issues while trying to make the function "field_file_load" work in a php script I've done to process an AJAX call.
I've read about bootstrapping drupal core elements inside, but it doesn't seem to work.
So far I've succesfully populated a Select Box using the data from another Select Box, making an AJAX call to this php file (which is in the drupal directory folder, in a theme to be precise)
<?php
$var = $_GET['q'];
$con = mysql_connect('*******', '******', '********');
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("drupal", $con);
$sql="SELECT DISTINCT xc.field_brand_value FROM node
INNER JOIN term_node AS tn ON node.vid = tn.vid
LEFT JOIN content_type_extra_content AS xc ON node.vid = xc.vid
WHERE tn.tid IN (SELECT th.tid FROM term_hierarchy AS th WHERE th.parent = '149')
AND xc.field_location_value = '".$var."'";
$result = mysql_query($sql);
echo(' <select name="brand" id="brand">
<option value="default" selected>Select a brand</option>
');
while($row = mysql_fetch_array($result))
{
echo('<option value="'.$row['field_brand_value'].'">'.$row['field_brand_value'].'</option>');
}
echo('</select>');
mysql_close($con);
?>
And this is working like a charm because all I have to do is connecting to the drupal db and fetch the desired values.
The problem arises when I want to fetch the url of some pictures (with a query that uses values from the first and second dropdown) and use the "file_field_load" to load the url of the given picture.
I get (obviously) a "call to undefined function" error.
So I tried bootstrapping drupal.
But it doesn't work anyway.
/** bootstrap Drupal **/
chdir("/path/to/drupal/site/htdocs");
require_once './includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
Since I don't have full access to the server where the site is hosted, assuming that drupal is convenientrly installed in the root, how can I figure out the path to drupal site htdocs ?
Moreover, does calling a full bootstrap (instead of just the needed part) can cause some problems?
So, to be brief:
1] how can I call a drupal function (in this case which comes from the filefiled module) in a non-drupal php script which resides however in the drupal directory?
2] Which is the correct way of bootstrapping?
3] Do I need to connect to the db (like in the previous working example) IN ADDITION to bootstrapping?
Or, finally. there's a different, speedier way you know how to do what I need to do?
Thanks in advance for any reply.
Hmm that's weird. If the FileField module is enabled, the function should be available. So maybe FileField is not actually enabled?
If that's the case you're gonna have to manually add the file that contains the function definition, which is the field_file.inc file in the module's directory, so you'd add that dependency to your bootstrapping code:
<?php
/** bootstrap Drupal **/
chdir("/path/to/drupal/site/htdocs");
require_once './includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
module_load_include('filefield', 'inc', 'field_file');
AFAIK what you're doing for bootstrapping Drupal from an outside script is the "correct" way.
Now, I'm not sure if, on a big picture level, whatever you're trying to do is a good idea at all... That is: You're making a little nonDrupal script which:
manually connects to the Drupal database with plain mysql functions instead of Drupal's DB API functions, in order to
fetch CCK information using a query that's 100% vulnerable to SQL injection, and
all of this put in a theme directory no less!
So you might want to rethink your angle of attack here, you know?. Maybe making a custom module for this.
But if you just have to do things this way (for reasons I can't think of), then at least use db_query so you don't have to do the whole mysql_connect() stuff, and do something like
<?php
db_query("YOUR BIG QUERY HERE... xc.field_location_value = '%s'", $var);
...for at least some degree of security.
I would also recommend that you browse the involved modules a bit (FileField, etc) to see if they have APIs (or at least some internal functions) that might return what you're trying to get through plain DB querying.
