I have one problem with RubyonRails.
I created a BDD with a table Article.
For add some line on this table, I do :
hello = Article.new(:title => title, :content => content)
hello.save
But I know another method exists with "table.create title: 'title'"
But it didn't work with more than one column.
Can someone tell me how I can do thing like :
article.create = title: 'title', content: 'content'

This has been driving me nuts for 2 days and I can't find an answer anywhere on Google so would really appreciate a little help..
I have a custom registration form on my website, which sends the data to a fairly standard PHPBB3 user_add process as follows:
$user_row = array(
'username' => request_var('createUsername',''),
'user_password' => phpbb_hash(request_var('createPassword','')),
'user_email' => request_var('createEmail',''),
'group_id' => '2',
'user_timezone' => '1.00',
// 'user_dst' => '0',
'user_lang' => 'en',
'user_type' => $user_type,
'user_actkey' => $user_actkey,
'user_ip' => $user->ip,
'user_regdate' => time(),
'user_inactive_reason' => $user_inactive_reason,
'user_inactive_time' => $user_inactive_time,
);
// Register user...
$user_id = user_add($user_row, $cp_data);
// If creating the user failed, display an error
if ($user_id === false)
{
trigger_error('NO_USER', E_USER_ERROR);
}
That works fine and I'm happy with it, however, I have created a custom profile field in the Admin Control Panel called 'ea_real_name' which I want to hold the user's real name. This corresponds to a field on the registration form called 'createRealName' (sent through as $_POST['createRealName'])
I know that user_add takes an optional field called 'cp_data', but I can't for the life of me work out how to format this data... Should it be an array (something like 'ea_real_name' => request_var('createRealName','') or something else?
PHPBB's wiki for the field is empty (https://wiki.phpbb.com/Custom_profile::submit_cp_field) so not much help...
Thanks! :-)
I was right in my assumption! It's an array with the field name prefixed by pf_.
Finally found an answer here: https://www.phpbb.com/community/viewtopic.php?f=71&t=1638905
$cp_data = array(
'pf_ea_real_name' => request_var('createRealName','')
);
Is the correct way to do it...
I have an issue related to filtering data in Netzke Grid.
column :user_id do |c|
c.editor = {xtype: :combobox, editable: false, min_chars: 2}
end
It is mentioned in the doc that,
A hash that will override the automatic editor configuration. For example, for one-to-many association column you may set it to {min_chars: 1}, which will be passed to the combobox and make it query its remote data after entering 1 character (instead of default 4).
Seems {min_chars: 1} is not working as expected.
Please see example below for simple Customers grid and let me know if it works for you. Netzke way is to use __ (double underscore) to define one-to-many associations. This gives you combobox and all necessary data bindings. I tried different ways to make min_chars property work, but it all failed. Could be a bug. In the end, the only thing that worked is to do it from init_component method.
class Customers < Netzke::Basepack::Grid
def configure(c)
super
c.model = 'Customer'
c.columns = [
{ name: :name, header: 'Customer Name' },
{ id: :country__name, name: :country__name, header: 'Country' }
]
end
js_configure do |c|
c.init_component = <<-JS
function() {
this.callParent();
Ext.ComponentManager.get('country__name').editor.minChars = 2;
}
JS
end
end
I need to restrict a category to a set of countries in Prestashop 1.5.
This restriction would prevent the shipping of a product belonging to such a category; as such, the users would still be able to see the products but they would not be able to buy them.
Ideally, I wanted to develop a module that would insert a list of countries (checkbox style, as in the Modules -> Payment page (AdminPayment)) inside a category's edit page, but I haven't been able to do so.
Why can't i simply paste the following code inside the renderForm() function?
Only the description is visible if i do so...
array(
'items' =>Country::getCountries(Context::getContext()->language->id),
'title' => $this->l('Country restrictions'),
'desc' => $this->l('Please mark the checkbox(es) for the country or countries for which you want to block the shipping.'),
'name_id' => 'country',
'identifier' => 'id_country',
'icon' => 'world',
),
EDIT:
I managed to get the list of countries working:
array(
'type' => 'checkbox',
'label' => $this->l('Restricted Countries').':',
'class' => 'sel_country',
'name' => 'restricted_countries',
'values' => array(
'query' => Country::getCountries(Context::getContext()->language->id),
'id' => 'id_country',
'name' => 'name'
),
'desc' => $this->l('Mark all the countries you want to block the selling to. The restrictions will always be applied to every subcategory as well')
),
Now, I can save these values by checking if the value "submitAddcategory" is being submitted in the postProcess function and by running an insert query there. Similarly, I can also load the IDs of the blocked countries from the database, but how can I tick the respective select boxes in the list of countries?
My initial "quick and dirty" idea was to use jQuery selectors inside a document.ready(), but the code gets inserted before everything else and, as such, it won't work because jQuery isn't even loaded yet.
How can this be done?
Cheers
I solved it by using the following code right before the end of the renderForm() function.
The Pièce de résistance was $this->fields_value, as sadly I didn't known of its existence.
public function getRestrictedCountries($obj)
{
// Loading blacklisted countries
$country = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS('
SELECT DISTINCT id_country
FROM `'._DB_PREFIX_.'category_country_restriction`
WHERE id_category = ' . (int)Tools::getValue('id_category') . ';');
$blacklisted_countries = array();
if (is_array($country))
foreach ($country as $cnt)
$blacklisted_countries[] = $cnt['id_country'];
// Global country list
$c_todos = Country::getCountries(Context::getContext()->language->id);
// Crossmatching everything
foreach ($c_todos as $c)
$this->fields_value['restricted_countries_'.$c['id_country']] = Tools::getValue('restricted_countries_'.$c['id_country'], (in_array($c['id_country'], $blacklisted_countries)));
}
PS: The table I am reading from is basically an associative table between 'category' and 'country'
i am trying to add product from frontend programatically following this link :
Magento: Adding new products programmatically
but i want to extend it to add custom options too to it .And i added the following code to it
$options = array();
$options[$sku] = array(
'title' => 'Option Title',
'type' => 'radio',
'is_require' => 1,
'sort_order' => 0,
'values' => array()
);
$options[$addvp['product']['sku']]['values'][] = array(
'title' => 'Option Value 1',
'price' => 0.00,
'price_type' => 'fixed',
'sku' => '',
'sort_order' => '1'
);
$options[$sku]['values'][] = array(
'title' => 'Option Value 2',
'price' => 89.00,
'price_type' => 'fixed',
'sku' => '',
'sort_order' => '1'
);
foreach($options as $sku => $option) {
$id = Mage::getModel('catalog/product')->getIdBySku($sku);
$product = Mage::getModel('catalog/product')->load($id);
if(!$product->getOptionsReadonly()) {
$product->setProductOptions(array($option));
$product->setCanSaveCustomOptions(true);
//$product->save();
}
}
but it prints this error instead of adding custom option to product.
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`vendor`.`catalog_product_entity`, CONSTRAINT `FK_CAT_PRD_ENTT_ATTR_SET_ID_EAV_ATTR_SET_ATTR_SET_ID` FOREIGN KEY (`attribute_set_id`) REFERENCES `eav_attribute_set` (`attribute_set_id`) ON DEL)
http://www.fontis.com.au/blog/magento/add-product-custom-options
Note:
The above link did what i want it to do. But one thing to be kept in mind that you must add the custom option to a product already exists/saved.
I had a similar issue. Turned out that the auto-generated SKU was somehow invalid or not properly saved on the new product I created for testing. The product was not invalid, as it did save properly on the first go, but when I revisited the product via the CMS and tried to click "save and continue" it suddenly prompted me to enter a SKU. When I re-entered the auto-generated sku it worked!
So the short answer would be: Check that your product exists by that SKU number. If it does, re-check that the SKU is being saved properly.
In my code I have three classes as follows: Forum, Forum::Thread and Forum::Post
What I want to do is create a belongs_to-relationship from the Forum::Post class to the Forum class and vice versa with a has_many, preferably without creating a custom function for it. (This is admittedly more of an intellectual exercise than a technical limitation or actual problem, but if it is possible, I would much like to know.)
The commented out lines contain my intention with the relationships, but in their current form, they fail to work. I've poked around in the documentation, but cannot find anything relevant to this specific case.
Any pointers?
The forum class:
package Schema::Result::Forum;
use Moose;
extends qw/DBIx::Class/;
__PACKAGE__->load_components (qw/Core/);
__PACKAGE__->table ('forum');
__PACKAGE__->add_columns (
id => {
is_auto_increment => 1,
data_type => 'integer',
},
);
__PACKAGE__->set_primary_key ('id');
__PACKAGE__->has_many (threads => 'Schema::Result::Forum::Thread');
#This is the interesting line
#__PACKAGE__->has_many (posts => 'threads' => 'forums' );
1;
The thread class:
package Schema::Result::Forum::Thread;
use Moose;
extends qw/DBIx::Class/;
__PACKAGE__->load_components (qw/Core/);
__PACKAGE__->table ('forum_thread');
__PACKAGE__->add_columns (
id => {
is_auto_increment => 1,
data_type => 'integer',
},
forum => {
data_type => 'integer',
},
);
__PACKAGE__->set_primary_key ('id');
__PACKAGE__->belongs_to (forum => 'Schema::Result::Forum');
__PACKAGE__->has_many (posts => 'Schema::Result::Forum::Post');
1;
The post class:
package Schema::Result::Forum::Post;
use Moose;
extends qw/DBIx::Class/;
__PACKAGE__->load_components (qw/Core/);
__PACKAGE__->table ('forum_post');
__PACKAGE__->add_columns (
id => {
is_auto_increment => 1,
data_type => 'integer',
},
thread => {
data_type => 'integer',
},
);
__PACKAGE__->set_primary_key ('id');
__PACKAGE__->belongs_to (thread => 'Schema::Result::Forum::Thread');
#This is the other interesting line
#__PACKAGE__->belongs_to (forum => 'thread' => 'forum');
1;
PS: Additional columns to hold actual content were omitted for brevity.
It looks like nested relationships aren't possible. has_many takes a single foreign class, which has a foreign key to the calling class.
The good news is $forum->threads->posts returns a single DBIx::Class::Resultset. It is not translated into SQL until needed, so when you call $forum->threads->posts->all() or even something like $forum->search_related('threads',{},{rows=>25})->posts->all(), it only runs a single query.
If your goal is to have a $post->forum, it can always be a method: sub forum{$_[0]->thread->forum}
What database and engine-type are you using? If you don't have foreign keys (like, for instance, with myisam tables in MySQL) then you'll have to provide the column names in your relationship statements.
