Yii Add to Cart functionality - database

I'm a Yii newbie. We have two MVC's in our test app: Apparatus and Order. I should be able to give a function where if a user clicks so, I import the selected row to Order, including the foreign key. It's like a makeshift cart. The problem is, since we are using GII, the CRUD and MODEL are already hard coded and it's confusing whether I should just put something like
$db->createCommand('INSERT INTO customer (name) VALUES (:name)', [':name' => 'Qiang',])->execute();
Does anybody have advice on how to go about it?

From your question I can see you are newbie to MVC as well. So I strongly recommend you to follow guide in http://www.yiiframework.com/doc/guide/1.1/en/basics.mvc and the fundamentals section.
Don't worry about Gii's auto generated codes. You can go ahead and customize them to achieve your goals.
For your question, There should be a create() function in OrderController if you have used Gii's CRUD generation. So you have to pass the apparatus_id to order controller from add to cart button/link. From there you get the foreign key.

Cakephp 3 - Building an entity over several forms/actions

This is a design question.
I'm trying to build a booking system in cakephp3.
I've never done something like this with cake before.
I thought the best way might be to -- as the post title suggests -- build up an entity over several forms/actions.
Something like choose location -> enter customer details -> enter special requirements -> review full details and pay
So each of those stages becomes an action within my booking controller. The view for each action submits its content to the next action in the chain, and i use patch entity with the request data, and send the result to the new action's view.
I've started to wonder if this is a good way to do it. One significant problem is that the data from each of the previous actions has to be stored in hidden fields so that it can be resubmitted with the new data from the current action.
I want the data from previous actions to be visible in a read only fashion so I've used the entity that i pass to the view to fill an HTML table. That's nice and it works fine but having to also store that same data in hidden fields is not a very nice way to do it.
I hope this is making sense!
Anyway, I thought I'd post on here for some design guidance as i feel like there is probably a better way to do this. I have considered creating temporary records in the database and just passing the id but i was hoping I wouldn't have to.
Any advice here would be very much appreciated.
Cheers.
I would just store the entity in the DB and then proceed with your other views, getting data from the DB. Pseudo:
public function chooseLocation() {
$ent = new Entitiy();
patchEntity($ent,$this->request->data);
if save entity {
redirect to enterCustomerDetails($ent[id]);
}
}
public function enterCustomerDetails($id) {
$ent = $this->Modelname->get($id);
// patch, save, redirect again ...
}

Show Opportunity related Contacts in Custom Object Field

I have the next issue.
I have a custom object called 'Application', and I have this requirement:
"Show all Contacts related to an Application. Create a field on Application object, must be read only".
I solve it with apex code. 'Application' has a lookup to Opportunity, Opportunity to Account, and all my contacts have AccountId, so this way, I get all the contacts using apex code in a trigger.
But, I've been ask to change this to a Formula field in Application object.
So, my issue is next. I'm not able to get all contacts with advance formula editor, because they're not part of any object. I have no master-detail relationship.
Does any one know how can I achieve this using configuration? I should not use apex code for this req.
Thank in advance guys.
I don't think you can do it.
In formulas / merge fields syntax there's no way to go "up, up then down" (Application -> Opportunity -> Account -> down to Contacts related list). There's also nothing that would let you loop through Contacts (and display what? Ids? Names? Emails?). Roughly speaking you can only go up through dots.
You might want to explore path of "cross object workflow" rules but I imagine that when I add a new Contact to Account it should somehow "spread itself" to all related Applications? There's no straight way to fire a workflow on delete too - so you'd eventually end up with inaccurate list.
I'd say trigger was a good solution. Maybe it ws unoptimized but if it has to be in a field - tough.
There might be a fairly simple way of achieving that by embedding a visualforce page within Application page layout.
This should be doable with pure Visualforce (so technically there will be no Apex code ;))
Something as simple as
<apex:relatedList list="Contacts" subject="Application__c.Opportunity__r.AccountId" />
would be a good start (if you want your own layout and not a rel. list - you should be still able to pull it off with <apex:repeat> or <apex:pageBlockTable>.
There's one BUT here: it's not a field, just a display trick. Forget about using it in reports, mobile applications etc.
Another way - would it be acceptable to be 1 click away from these contacts? You could make a report "Account with Contacts", filter it by Id of one Account and later use "URL hacking" to change the filter depending on from which Application you'll click it. This link could be either a formula field or a real custom button/link. Technically - it's pure config, no apex & VF.
You can read more about URL hacking at Ray Dehler's excellent post and specifically about dynamic Reports here or here.

How to use Yii with a multilingual database model?

I’m having a problem getting the data from my database which I created to be completely multilingual, and I hope someone here can help me.
I’ve split up all my tables in 2 parts; the “universal” table (does not contain any text that needs to be translated) and the table which contains all the fields that need to be translated with their translations.
Example tables:
base_material
id
picture
base_material_i18n
base_material_id
localization_id
name
description
review_status
review_notes
localization
id
language_name
Query to get the translations (using English (en) as a fall-back language if there is no translation available):
SELECT o.id
, o.type
, o.code
, o.position
, ifnull(t.name,d.name) name
, ifnull(t.description,d.description) description
FROM base_material o
INNER JOIN base_material_i18n d
ON ( o.id=d.base_material_id)
LEFT OUTER JOIN base_material_i18n t
ON ( d.base_material_id=t.base_material_id AND t.localization_id='nl' )
WHERE d.localization_id='en'
My question is how I can automatically get those translations (with the fall-back language as in this query) attached to my model in Yii when I’m searching for the base_material objects? (This is only 1 example table, but almost all my tables (20+) are built in this way, so if possible I would be needing something flexible)
An example of an existing system using what I would need is Propel: http://propel.posterous.com/propel-gets-i18n-behavior-and-why-it-matters
Any ideas how to go about doing that? I’ve checked the existing Yii extensions regarding multilingual sites (like Multilingual Active Record), but they all use a different database design (general information+fall-back language in the main table, translations in the i18n table), and I’m not sure how to change those extensions to use my kind of DB model.
If someone knows of a way to change that existing extension so it can use my kind of DB scheme, then that would be absolutely brilliant and probably the best way to do this.
Edit: I've added a bounty because I still can't find anything on how to let Propel work with Yii (there does exist an extension for Doctrine, but Doctrine doesn't support this kind of DB model with translations either), nor any more information as to how to deal with this using an existing Yii extension or with scopes.
Edit: 98 times viewed but only 3 upvotes and 1 comment. I can't help feeling like I'm doing something wrong here, be it in my question or application/database design; either that or my problem is just very unique (which would surprise me, as I don't think my multilingual database design is that absurd ;-). So, if anyone knows of a better all-round solution for multilingual sites with Yii and/or Propel (apart from the current extensions which I really don't like due to the duplication of text fields) or something similar, please let me know as well.
Thanks in advance!
Have you tried http://www.yiiframework.com/extension/i18n-columns/ (based on http://www.yiiframework.com/extension/stranslateablebehavior/)?
It is an alternate, simpler, approach by adding new table fields in the style of {field}_{language code}, and then setting the translated field in the original model to the current language's translation on afterFind.
In essence, it will get you up and running with translatable fields with the translated content being fetched "automatically", for good and bad :). Adding and removing languages (=columns) is done using migrations.
I am also looking for a generic solution to implement i18n into Yii models.
Recently I chose a very similar database schema for a project like you.
The only difference is, that I am not using a separate language table, I store the language information in the i18n table.
The following solution is without a custom SQL statement, but I think this could be implemented with relation params, anyway, if you're working with foreign key in your database (eg. MySQL InnoDB) gii will create relations between your base_material and base_material_i18n table, like
class BaseMaterial extends CActiveRecord
public function relations()
{
return array(
'baseMaterialI18ns' => array(self::HAS_MANY, 'base_material_i18n', 'id'),
);
}
class BaseMaterialI18n extends CActiveRecord
public function relations()
{
return array(
'baseMaterial' => array(self::BELONGS_TO, 'base_material', 'id'),
);
}
Now you'd be able to access your translations by using the object notation for relations.
$model = BaseMaterial::model()->with('baseMaterialI18ns')->findByPk(1);
foreach($model->baseMaterialI18ns AS $translation) {
if ($translation->language != "the language I need") continue:
// do something with translation data ...
}
I thought about creating a behavior or base class for those models which would act a as helper for managing the translations - pseudo code:
I18nActiveRecord extends CActiveRecord
protected $_attributesI18n;
// populate _attributesI18n on query ...
public function __get($name) {
if(isset($this->_attributesI18n['language_I_need'][$name]))
return $this->_attributesI18n[$name];
else if(isset($this->_attributesI18n['fallback_language'][$name]))
return $this->_attributesI18n[$name];
else
parent::__get();
}
CActiveRecord __get() source
There is more work to be done to find the needed i18n record, also you could further limit the with() option to improve performance and reduce parsing on the PHP side.
But there may be different use cases how to determine the value, e.g. all translations, translation or fallback, no fallback (empty value).
Scenarios could be helpful here.
PS: I would be up for a github project!
You can try to use a simple multilingual CRUD extension.
it is very simple to use and modificate. you just need to add language field to your table.
just watch description here: http://all-of.me/yii-multilingual-crud/
it is in alpha state, but tried on a few projects. you can easily modificate it or contact author to fix or add features

Salesforce.com visualforce between 2 objects

In salesforce I need to create a visualforce page that includes the fields of 2 objects. The first object is the QUOTE object. The second objects is a custom object with several fields.
I want to create a visualforce page that shows the records of both QUOTE and the new object. Can I do this without creating a custom controller? If no any hints on the code for this new controller?
Can I do calculations between fields in a visualforce page?
Ideally I want this page to appear as soon as the QUOTE is set to ACCEPTED
1: You can't do this without a custom controller unfortunately, unless one object is related to the other and you're just happy displaying it as a related list on the parent object's page. For calculations you could use rollup summaries for some basic sums etc..
As for a custom controller, have a look at field sets for a super easy way to get fields into a VF page, you essentially configure groups of fields on your objects and then you can stick those groups onto a page with minimal markup.
2: For fields with complex calculations you'll want to do the sums in the controller and then expose the results through variables onto the page in the usual manner.
3: Not really possible without creating a custom edit page in the first place — you'd be better off having a button on the quote page to open up the Visualforce page, that page can simply display an error if the quote is not yet accepted. There are some other alternatives that might work though, like using a forumla field to generate a link to the page when the status is as you desire.
I'm happy to elaborate on any of this, but the fact that you're asking about number 2 would suggest to me that you don't have much experience developing on the platform (not a dig, just an observation), so unless you're comfortable coding in other environments you could find this quite tricky. That said, you're on stackoverflow so I'm thinking you probably know a little about coding at least!

Cakephp Tagging - Auto Save new Tags and Tag Relations

I read a lot about tagging in CakePHP but I can't find a "clean" way to save a Post and the Tags to this post. I have all which is necessary the Post Table, Model and Controller, the Tag table, Model and Controller and the posts_tags table. I created the HABTM Associations in the Post and the Tag Model.
If I want to save a new post, I want that CakePHP automagically saves the tags associated to that post, but I can't find the right way for that. In most of the tutorials you have to use a "helper" Function (http://www.jamesfairhurst.co.uk/posts/view/full_cakephp_application_part_5 => "_parse_genres") or something like that, but I thought the deal with CakePHP is it, that this is all done by Cake once you set it up right.
So my question, is there a "clean"-Cake-way to do it, or do I have to use a helper function?
I find it very hard to believe that you didn't find a "proper" way to handle HABTM. There are many, many articles about it. I believe that Cake will save your tags if you set your data array properly. A quick search on The Bakery:
http://bakery.cakephp.org/articles/search/3/HABTM
Will reveal enough. My guess is that you're looking for this:
http://bakery.cakephp.org/articles/view/simple-tagging-behavior
(Note that there is a component which does the same thing, but model behaviour is the right way to go)
