Codeigniter loading model - codeigniter-3

In a Codeigniter application I have the following code:
$this->load->model('movie_model', 'movie_manager');
My assumption is we can only load single model using $this->load->model() . I like to know what the 'movie_manager' stands for.

If you would like your model assigned to a different object name you can specify it via the second parameter of the loading method:
$this->load->model('model_name', 'foobar');
$this->foobar->method();
Docs.

if you want to load many models, you can do like this:
$this->load->model(array('movie_model', 'movie_manager'));
assuming that movie_model, and movie_manager are your model names here...

the second parameters used, if ever you want to rename your object name.
for example:
$this->load->model('movie_model', 'movie_manager');
instead of calling your method like this:
$this->movie_model->method();
you can call it like this now:
$this->movie_manager->method();

Property Mapping Exception in Helhum upload example

I am using helhum File Upload Demo to upload the images. But currently i got below error.
Exception while property mapping at property path "images.0":Property "name" was not found in target object of type "XXXX\XXXXX\Domain\Model\FileReference
Please help here.. How can i move forward.
Thanks in advace.
If you followed the example extension, you are maybe missing the registration of UploadedFileReferenceConverter and ObjectStorageConverter in your ext_localconf.php. Took me a day to find that one:
ext_localconf.php
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerTypeConverter('Vendor\\EXT\\Property\\TypeConverter\\UploadedFileReferenceConverter');
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerTypeConverter('Vendor\\EXT\\Property\\TypeConverter\\ObjectStorageConverter');
In the initializeUpdateAction (or initializeCreateAction) you have to use the name of the parameter in the updateAction (or createAction) as argument.
If your updateAction looks like this:
public function updateAction(\Classname $yourObject)
You have to call the helhum function with the argument:
$this->setTypeConverterConfigurationForImageUpload('yourObject');
As a small hint for later problems: In the setTypeConverterConfigurationForImageUpload function you should register your own file attributes if they are not named image and/or imageCollection.0 like in the example.

Get object in i18n form

Inside embedded i18n form i need to get object.
In this example i got ArtistImageTranslation object, but i need ArtistImage.
Can somebody help me, how to get this?
class ArtistImageTranslationForm extends BaseArtistImageTranslationForm
{
public function configure()
{
$this->getObject();
....
}
}
Have you tried the following?
$artistimage = $this->getObject()->getArtistImage();
I spent half of day today on the same problem and looks like I finally found something ;)
First, if you need to access the fields which are in the "Translation" part of the table you can access them directly from the Object contained in the form. Just access the properties without using the getter (I know it's not the nice way but it works). So you can use something like:
$this->getObject()->id;
$this->getObject()->translated_name;
etc.
If you really need the original object you can access it like this:
$this->getObject()->getTable()->getRelation('ArtistImage')
->fetchRelatedFor($this->getObject());
Hope this helps.
Try :
$artistimage = $this->getObject()->artistImage;
or
$artistimage = $this->getObject()->artist_image;

Zend Framework / Form Element is rendering as a text box rather than a dropdown box

I have the following in a config.ini file: (Zend_Form_Element)
site_status.name = "site_status"
site_status.type = "select"
site_status.label = "Status"
site_status.options.multiOptions.active.key = "Active"
site_status.options.multiOptions.active.value = "Active"
site_status.options.multiOptions.active.key = "Inactive"
site_status.options.multiOptions.active.value = "Inactive"
As you can see this is supposed to be a dropdown (select) box, however it is being rendered as a standard text box. What am I doing wrong?
--> Edit
Rather than tying the elements to a form, I am trying to tie them to a database: In my code it would look something like this:
[{tablename}] // the table name would represent a section in the ini
{column}.name = "{column_name/form_field_id}";
{column}.type = "{form_element_type}"
{column}.label = "{form_element_label}"
...
From there I would pull in the database table(s) that the form would represent data for (one or more tables as necessary). As far as the reasoning for this approach is that (down the road), I want to define (either by ini or some other storage method), a configuration file that would be a list of fields/elements that belong to a specific form (that a non-programmer type could easily edit), that the 'generic' form class would read, pull in the element info, and create the form on the fly.
I do realize however this poses another problem which I haven't yet figured out, and that is how to use table lookups for select elements (without coding the database retrieval of the lookup into the form, so that a non-user could easily just define it without any programming, purely configuration, but that is a whole other topic not part of my question here. (and I think I have viable ideas/solutions to that part of the problem anyhow) -- extra config entries and a generic routine pretty much.
I hope that clarifies my thought process and reason why I am doing it the way I am in the example above.
I have not yet played with using a Zend_Config to construct an instance of Zend_Form.
But a look at the code suggests that Zend_Form::addElement() doesn't directly take a Zend_Config instance as a param. Rather, it looks like you need pass your Zend_Config instance to the form constructor. It also seems that the config format needs to be a little deeper in order to map config keys to setXXX() calls.
In path/to/config/myForm.ini:
[myForm]
myForm.elements.site_status.name = "site_status"
myForm.elements.site_status.type = "select"
myForm.elements.site_status.label = "Status"
myForm.elements.site_status.options.multiOptions.active.key = "Active"
myForm.elements.site_status.options.multiOptions.active.value = "Active"
myForm.elements.site_status.options.multiOptions.inactive.key = "Inactive"
myForm.elements.site_status.options.multiOptions.inactive.value = "Inactive"
Then instantiating:
$formConfig = new Zend_Config_Ini('path/to/config/myForm.ini', 'myForm');
$form = new Zend_Form($formConfig);
Not tested, but looking at this example:
Using Zend_Form with Zend_Config - Andrew Vayanis
it feels like it should go something like the above.
Update
In view of the comments/feedback from #Aaron, two more approaches.
We could extend Zend_Form, implementing a method called something like addElementByConfig in which we would pass the shallow Zend_Config instance that describes the element itself. In fact, we could even just override addElement(), taking a recursive approach: if the first param is an instance of Zend_Config, then call addElement() using the component data.
If the atomicity and re-usability are the primary benefits we seek in using Zend_Config to describe an element, then perhaps we just make a custom element extending Zend_Form_Element. Then we could use these elements in any forms we wish.

Symfony form gets messy when calling getObject() in form configuration

I have a Strain model that has a belongsTo relationship with a Sample model, i. e. a strain belongs to a sample.
I am configuring a hidden field in the StrainForm configure() method this way:
$defaultId = (int)$this->getObject()->getSample()->getTable()->getDefaultSampleId();
$this->setWidget('sample_id', new sfWidgetFormInputHidden(array('default' => $defaultId)));
Whenever I create a new Strain, the $form->save() fails. The debug toolbar revealed that it tries to save a Sample object first and I do not know why.
However, if I retrieve the default sample ID using the table it works like a charm:
$defaultId = (int)Doctrine_Core::getTable('Sample')->getDefaultSampleId();
$this->setWidget('sample_id', new sfWidgetFormInputHidden(array('default' => $defaultId)));
My question here is what can be happening with the getObject()->getSample()... sequence of methods that causes the StrainForm to think it has to save a Sample object instead of Strain.
I tried to debug with xdebug but I cannot came up with a clear conclusion.
Any thoughts?
Thanks!!
When you call getSample its creating a Sample instance. This is automatically attached to the Strain object, thus when you save you also save the Sample.
An altenrative to calling getSample would be to chain through Strain object to the Sample table since i assume youre only doing this so your not hardcodeing the Sample's name in related form:
// note Sample is the alias not necessarily the Model name
$defaultId = Doctrine_Core::getTable($this->getObject()->getTable()->getRelation('Sample')->getModel())->getDefaultId();
Your solution probably falls over because you can't use getObject() on a new form (as at that stage the object simply doesn't exist).
Edit: Why don't you pass the default Sample in via the options array and then access it from within the form class via $this->getOption('Sample') (if I remember correctly)?

Can I do more than one form for the same model class in symfony?

Well, imagine that we have a register form of a class Customer and we only ask three fields (name,surname,email) and after, when this user logged first time we want to complete this information.
First, we have in lib/form/doctrine a file called 'CustomerForm.class.php' wich is generated automatic on command line. In this file we 'setup' only 3 fields and validators and if we wanna use we do something like that:
$this->form = CustomerForm();
Second, we create manual another form named 'CustomerFormStep1.class.php' where we can setup for validate the other fields. But when we do..
$this->form = CustomerFormStep1();
it returns error: Fatal error: Class 'CustomerFormStep1' not found
What is wrong?
Thanks.
Assuming you have the form defined as:
class CustomerFormStep1 extends sfForm
or similar (sfFormDoctrine etc), and named correctly like you say (CustomerFormStep1.class.php) and in lib/form, then Symfony should just pick the definition up fine. Did you clear the cache after creating and placing it in the right place? (symfony cc).
Create the new CustomerFormStep1 class as #richsage instructed. Then, in your actions you can write something like:
public function executeLogin(){
//before login
$this->form = new CustomerForm();
}
public function executeLoggedIn(){
$this->form = new CustomerFormStep1();
//other steps
}
Haven't you read the tutorial? Extending forms is perfectly described in context with reh admin generator and can of course be applied to any case.
