• Getting Started with CacheMoney

  - by Matt Grande

  I recently installed cache-money. After some difficulties getting memcached and cache-money set up, I thought I had it working. It cached the one query on my login page fine. I login, and go to my message index page and get this error: indices delegated to @cache_config.indices, but @cache_config is nil: Slug(id: integer, name: string, sluggable_id: integer, sequence: integer, sluggable_type: string, scope: string, created_at: datetime) Searching for the first part of that error message returns 0 hits on Google, so I'm at a loss on where to even begin. Any suggestions?

• How to display Django SelectDateWidget on one line using crispy forms

  - by Scott Johnson

  I am trying to display the 3 select fields that are rendered out using Django SelectDateWidget on one line. When I use crispy forms, they are all on separate rows. Is there a way to use the Layout helper to achieve this? Thank you! class WineAddForm(forms.ModelForm): hold_until = forms.DateField(widget=SelectDateWidget(years=range(1950, datetime.date.today().year+50)), required=False) drink_before = forms.DateField(widget=SelectDateWidget(years=range(1950, datetime.date.today().year+50)), required=False) helper = FormHelper() helper.form_method = 'POST' helper.form_class = 'form-horizontal' helper.label_class = 'col-lg-2' helper.field_class = 'col-lg-8' helper.add_input(Submit('submit', 'Submit', css_class='btn-wine')) helper.layout = Layout( 'name', 'year', 'description', 'country', 'region', 'sub_region', 'appellation', 'wine_type', 'producer', 'varietal', 'label_pic', 'hold_until', 'drink_before', ) class Meta: model = wine exclude = ('user', 'slug', 'likes')

• Changing data in a django modelform

  - by Matt Hampel

  I get data in from POST and validate it via this standard snippet: entry_formset = EntryFormSet(request.POST, request.FILES, prefix='entries') if entry_formset.is_valid(): .... The EntryFormSet modelform overrides a foreign key field widget to present a text field. That way, the user can enter an existing key (suggested via an Ajax live search), or enter a new key, which will be seamlessly added. I use this try-except block to test if the object exists already, and if it doesn't, I add it. entity_name = request.POST['entries-0-entity'] try: entity = Entity.objects.get(name=entity_name) except Entity.DoesNotExist: entity = Entity(name=entity_name) entity.slug = slugify(entity.name) entity.save() However, I now need to get that entity back into the entry_formset. It thinks that entries-0-entity is a string (that's how it came in); how can I directly access that value of the entry_formset and get it to take the object reference instead?

  I'm getting a Parse error: syntax error, unexpected T_DOUBLE_ARROW PHP on line 47, which is 'post_content' => $thisShow['content'], Anyone got any ideas why? protected function _saveShow($thisShow) { $saveData = array( 'mid' => $this->_saveAsUserId, 'post_title' => $thisShow['title'], 'post_name' => slug($thisShow['title'], 'post_content' => $thisShow['content'], 'post_date' => date('Y-m-d H:i:s'), 'post_date_gmt' => date('Y-m-d H:i:s'), 'category_id' => 4, 'post_author' => 0, 'category_name' => $thisShow['category_name'] ); // $this->_database->insert('wp_posts', $saveData); }

• Getting a specific number of JSON items with jQuery from tumblr feed

  - by Kevin Whitaker

  Hello all. I'm trying to populate a page with X entries from my tumblr feed, and I'm wondering how I can only pull that X number from the JSON object it returns. Here's my code, pulled from another Stack Overflow post and modified: //Tumblr retrieval $.getJSON("http://tumblr-address/api/read/json?callback=?", function(data) { $.each(data.posts, function(i,posts){ var title = this["regular-title"]; var type = this.type; var date = this.date; var url = this["url-with-slug"]; $('#sideRail ol').prepend('<li><p><a href=' +url +'>' + title + '</a></p><p>' + date + '</p></li>'); }); }); I've tried using a while loop with a counter, but it just repeats everything X times before moving on to the next item in the list. Thanks for any help.

• how to write re-usable views in django?

  - by rz

  These are the techniques that I use regularly to make my views reusable: take the template_name as an argument with a default take an optional extra_context which defaults to empty {} right before the template is rendered the context is updated with the extra_context for further re-usability, call any callable in extra_context.values() whenever the view deals with a queryset, there is a queryset argument with a default whenever the view needs a particular object from the ORM, it attempts to fetch it using any "id" parameter in several ways (e.g. as a slug, as a database id) (this may be a bad practice...) First, Should I add anything to my list? Should I remove anything from my list? The items accommodates a large number of cases. However, whenever an app extends a model of another in some way (e.g. adding a field or changing the behavior in some way) I end up writing my own views and only reusing the model. Is this normal?

• Storing website hierarchy in Sql Server 2008

  - by Mika Kolari

  I want to store website page hierarchy in a table. What I would like to achieve is efficiently 1) resolve (last valid) item by path (e.g. "/blogs/programming/tags/asp.net,sql-server", "/blogs/programming/hello-world" ) 2) get ancestor items for breadcrump 3) edit an item without updating the whole tree of children, grand children etc. Because of the 3rd point I thought the table could be like ITEM id type slug title parentId 1 area blogs Blogs 2 blog programming Programming blog 1 3 tagsearch tags 2 4 post hello-world Hello World! 2 Could I use Sql Server's hierarchyid type somehow (especially point 1, "/blogs/programming/tags" is the last valid item)? Tree depth would usually be around 3-4. What would be the best way to achieve all this?

• Best solution for managing navigation (and marking currently active item) in CakePHP

  - by Nathan

  So I have been looking around for a couple hours for a solid solution to handling site navigation in CakePHP. Over the course of a dozen projects, I have rigged together something that works for each one, but what I'm looking for is ideally a CakePHP plugin that handles the following: Navigation Model Component for handing off to the view Element View Helper for displaying the navigation (with control over sublevels displayed and automatically determining the "active" item based on URL and/or controller/model/slug Admin pages for managing a tree of navigation Any suggestions for an all-in-one solution or even the individual components would be very appreciated! Or even suggestions on how you have handled it in the past

• Incorporate Wordpress into Kohana 3

  - by alex

  I now need to make a Kohana 3 site have a Wordpress blog. I've seen Kerkness' Kohana For Wordpress, but it seems to be the opposite of what I want. Here are the options I have thought of Style a template to look exactly like the Kohana site (time consuming, non DRY and may not work) Include the blog within an iframe (ugly as all hell) cURL the Wordpress pages in. This of course means I will need to create layers between comment posting, etc, which sounds like too much work. Is there any way I can include a Wordpress blog within an existing Kohana application? Do you have any suggestions? Thanks Update Forgot to mention I have already programmed a model in Kohana to open pages based on their slug. Now I want to put blog content in there, and have the comments and other bits work. I also have installed WP e-Commerce and am wondering if there is any chance I can get that to work.

• Django says the "id may not be NULL" but why is it?

  - by Oli

  I'm going crazy today. I just tried to insert a new record and it threw back a "post_blogpost.id may not be NULL" error. Here's my model: class BlogPost(models.Model): title = models.CharField(max_length=100) slug = models.SlugField(max_length=100) who = models.ForeignKey(User, default=1) when = models.DateTimeField() intro = models.TextField(blank=True, null=True) content = models.TextField(blank=True, null=True) counter = models.PositiveIntegerField(default=0) published = models.BooleanField(default=False) css = models.TextField(blank=True, null=True) class Meta: ordering = ('-when', 'id') There are a number of functions beneath the model too but I won't include them in full here. Their names are: content_cache_key, clear_cache, __unicode__, reads, read, processed_content. I'm adding through the admin... And I'm running out of hair.

• Can't create admin user on Heroku

  - by Nick5a1

  I am new to rails and I have gone through Kevin Skoglund's Ruby on Rails 3 Essential Training course on Lynda.com. Through the course you set up a simple cms, which I did. It doesn't cover Git or deployment but I've pushed my simple cms to github (https://github.com/nick5a1/Simple_CMS) and deployed to Heroku (http://nkarrasch.herokuapp.com/). In order to deploy to Heroku I followed the Heroku setup guide (https://devcenter.heroku.com/articles/rails3) and switched my database from MySQL to PostgreSQL. As instructed I changed gen'mysql2' to gen 'sqlite3' in my Gemfile and ran bundle install before pushing. I then ran heroku run rake db:migrate. I'm running into 2 problems. When I try to log in (http://nkarrasch.herokuapp.com/access) I get an error "We're sorry, but something went wrong". I should instead be getting a flash message with invalid username/password combination. This is what I'm getting on my test environment on my local machine. Secondly, when I log into the Heroku console to create and create an admin user, when I try to save that user I get the following error: irb(main):004:0> user.save (1.2ms) BEGIN AdminUser Exists (1.9ms) SELECT 1 AS one FROM "admin_users" WHERE "admin_users"."username" = 'Nick5a1' LIMIT 1 (1.7ms) ROLLBACK => false Any advice on how to troubleshoot would be greatly appreciated :).

• Zend_Session: unserialize session data

  - by takeshin

  I'm using session SaveHandler to persist session data in the database. Sample session_data column from the database: Messenger|a:1:{s:13:"page_messages";a:0:{}}userSession|a:1:{s:7:"referer";s:32:"http://cms.dev/user/profile/view";}Zend_Auth|a:1:{s:7:"storage";O:19:"User_Model_Identity":3:{s:2:"id";s:1:"1";s:8:"username";s:13:"administrator";s:4:"slug";s:13:"administrator";}} I want to delete Zend_Auth object from this session data. How can I unserialize those objects and remove object I need? I suspect, that I don't have to write my custom parser, that Zend_Session already has a method to do this. I have tried different combinations of unserialize but it still returns false. I'm using autoloader from ZF 1.10.2 and Doctrine 1.2

• Ajax Fancy Capture in CakPHP

The plugin can be found here: http://www.webdesignbeach.com/beachbar/ajax-fancy-captcha-jquery-plugin What I have tried: in the controller: public function index($slug = null, $capture = false) { if($capture AND $capture =="get_capture"){ $rand = rand(0,4); $_SESSION['captcha'] = $rand; echo $rand; die; } if (!empty($this->data) && $_POST['captcha'] == $_SESSION['captcha']) { .... save the post } } in the view: $selectURL = " $(function() { $('.ajax-fc-container').captcha({ borderColor: 'silver', captchaDir: 'http://localhost/img/capture', url: 'http://localhost/contacts/index/contacts/get_capture', formId: 'MessageIndexForm', }); });"; $this->Html->scriptBlock($selectURL, array('inline' => false)); also I have tried with url: 'http://localhost/js/capture.php' which is the original file coming with the plugin but still not working.

• WordPress: don't show 404 when no posts exist

  - by philfreo

  Currently there is a bug in WordPress if you have a Posts Page set under: Settings-Reading-A Static Page-Posts Page If there are posts, than the page (e.g. with a slug called news) displays the post, and uses index.php from the theme. But, with this configuration, if there are no posts, then it calls the theme's 404 page. This is definitely a bug, and has been submitted (Ticket #10822). It should be letting index.php show whatever it wants upon !have_posts(), but right now the page doesn't seem to be called at all. My question is: is there a workaround for this bug without modifying core wp files? I'd be open to a plugin, theme changes, a custom page template, htaccess changes, etc.

• Regular Expression for $_GET query strings

  - by sandelius

  Hi there! I'm trying to find a regular expression for $_GET query strings. I have an array like this: private $_regexp = array( ':id' => '[0-9]+', ':year' => '[12][0-9]{3}', ':month' => '0[1-9]|1[012]', ':day' => '0[1-9]|[12][0-9]|3[01]', ':slug' => '[a-zA-Z0-9-]+', ':query' => '...' ); and I loop throw them to see if I have a matching wildcard like this: if ( array_key_exists($matches[0], $this->_regexp) ) { return '^('.$this->_regexp[$matches[0]].')$'; } All other regexp go throw but I've tried a whole lot of different regexp to find: ?anything=anything can't figure it out, googled like h..l but can't find anything. I've tried, for example something like this: (\?)(.*)(=)(.*) but without result... Any regexp gurus here? / Tobias

• Polymorphic associations in CakePHP2

  - by Joseph

  I have 3 models, Page , Course and Content Page and Course contain meta data and Content contains HTML content. Page and Course both hasMany Content Content belongsTo Page and Course To avoid having page_id and course_id fields in Content (because I want this to scale to more than just 2 models) I am looking at using Polymorphic Associations. I started by using the Polymorphic Behavior in the Bakery but it is generating waaay too many SQL queries for my liking and it's also throwing an "Illegal Offset" error which I don't know how to fix (it was written in 2008 and nobody seems to have referred to it recently so perhaps the error is due to it not having been designed for Cake 2?) Anyway, I've found that I can almost do everything I need by hardcoding the associations in the models as such: Page Model CREATE TABLE `pages` ( `id` int(11) NOT NULL AUTO_INCREMENT, `title` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `slug` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `created` datetime NOT NULL, `updated` datetime NOT NULL, PRIMARY KEY (`id`) ) <?php class Page extends AppModel { var $name = 'Page'; var $hasMany = array( 'Content' => array( 'className' => 'Content', 'foreignKey' => 'foreign_id', 'conditions' => array('Content.class' => 'Page'), ) ); } ?> Course Model CREATE TABLE `courses` ( `id` int(11) NOT NULL AUTO_INCREMENT, `title` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `slug` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `created` datetime NOT NULL, `updated` datetime NOT NULL, PRIMARY KEY (`id`) ) <?php class Course extends AppModel { var $name = 'Course'; var $hasMany = array( 'Content' => array( 'className' => 'Content', 'foreignKey' => 'foreign_id', 'conditions' => array('Content.class' => 'Course'), ) ); } ?> Content model CREATE TABLE IF NOT EXISTS `contents` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `class` varchar(30) COLLATE utf8_unicode_ci NOT NULL, `foreign_id` int(11) unsigned NOT NULL, `title` varchar(100) COLLATE utf8_unicode_ci NOT NULL, `content` text COLLATE utf8_unicode_ci NOT NULL, `created` datetime DEFAULT NULL, `modified` datetime DEFAULT NULL, PRIMARY KEY (`id`) ) <?php class Content extends AppModel { var $name = 'Content'; var $belongsTo = array( 'Page' => array( 'foreignKey' => 'foreign_id', 'conditions' => array('Content.class' => 'Page') ), 'Course' => array( 'foreignKey' => 'foreign_id', 'conditions' => array('Content.class' => 'Course') ) ); } ?> The good thing is that $this->Content->find('first') only generates a single SQL query instead of 3 (as was the case with the Polymorphic Behavior) but the problem is that the dataset returned includes both of the belongsTo models, whereas it should only really return the one that exists. Here's how the returned data looks: array( 'Content' => array( 'id' => '1', 'class' => 'Course', 'foreign_id' => '1', 'title' => 'something about this course', 'content' => 'The content here', 'created' => null, 'modified' => null ), 'Page' => array( 'id' => null, 'title' => null, 'slug' => null, 'created' => null, 'updated' => null ), 'Course' => array( 'id' => '1', 'title' => 'Course name', 'slug' => 'name-of-the-course', 'created' => '2012-10-11 00:00:00', 'updated' => '2012-10-11 00:00:00' ) ) I only want it to return one of either Page or Course depending on which one is specified in Content.class UPDATE: Combining the Page and Course models would seem like the obvious solution to this problem but the schemas I have shown above are just shown for the purpose of this question. The actual schemas are actually very different in terms of their fields and the each have a different number of associations with other models too. UPDATE 2 Here is the query that results from running $this->Content->find('first'); : SELECT `Content`.`id`, `Content`.`class`, `Content`.`foreign_id`, `Content`.`title`, `Content`.`slug`, `Content`.`content`, `Content`.`created`, `Content`.`modified`, `Page`.`id`, `Page`.`title`, `Page`.`slug`, `Page`.`created`, `Page`.`updated`, `Course`.`id`, `Course`.`title`, `Course`.`slug`, `Course`.`created`, `Course`.`updated` FROM `cakedb`.`contents` AS `Content` LEFT JOIN `cakedb`.`pages` AS `Page` ON (`Content`.`foreign_id` = `Page`.`id` AND `Content`.`class` = 'Page') LEFT JOIN `cakedb`.`courses` AS `Course` ON (`Content`.`foreign_id` = `Course`.`id` AND `Content`.`class` = 'Course') WHERE 1 = 1 LIMIT 1

• Wordpress - Plugin - Administration - ?

  - by Goran

  Hi, I'm building a Wordpress plugin and I added a menu page which serves for management of "Vendor" entities that are kinda similar to the existing User entities. I have a list page similar to Users List, with Edit button for every record and when I click on the "Edit" button I should be taken to the "Edit Vendor" (which does not have its submenu item in the admin menu) page for that vendor. Everything is stored in the "plugins/wp_vendors" folder. Question: What URL should I use for opening that Edit page? How should a slug be registered for the Edit Vendor page? PS. Vendor List is added to the admin menu with add_menu_page('Vendors', 'Vendors', 8, 'C:\wordpress\wp-content\plugins\wp-vendors\vendors-list.php'); And I can open the List page with http://localhost/wp-admin/admin.php?page=wp-vendors/vendors-list.php Can anyone help me on this?

• manyToManyField question

  - by dotty

  Hay guys, I'm writing a simple app which logs recipes. I'm working out my models and have stumbled across a problem My Dish models needs to have many Ingredients. This is no problem because i would do something like this ingredients = models.ManyToManyfield(Ingredient) No problems, my dish now can have many ingrendients. However, the problem is that the ingredient needs to come in different quantities. I.E 4 eggs, 7 tablespoons sugar My Ingredient Model is very simple at the moment class Ingredient(models.Model): name = models.TextField(blank=False) slug = models.SlugField(blank=True) How would i go about work out this problem? What fields would i need to add, would i need to use a 'through' attribute on my ManyToManyfield to solve this problem?

  I am having a problem with duplicate blog post coming back when i run the linq statement below. The issue that a blog post can have the same tag more then once and that's causing the problem. I know when you use criteria you can do the followingcriteria.SetResultTransformer(new DistinctRootEntityResultTransformer()); How can I do the same thing with linq? List<BlogPost> result = (from blogPost in _session.Linq<BlogPost>() from tags in blogPost.Tags where tags.Tag == tag && blogPost.IsPublished && blogPost.Slug != slugToExclude orderby blogPost.DateCreated descending select blogPost).Distinct() .Skip(recordsToSkip).Take(pageSize).ToList();

"); while ($row = $db->sql_fetchrow($result)) { //fetching other $vars ---- $tags_id = explode(" ",$row['tags']); $c = count($tags_id); for($i=1;$i<$c-1;$i++){ list($tag_name,$slug) = $db->sql_fetchrow($db->sql_query( 'SELECT `tag`,`slug` FROM `bt_tags` WHERE `tid` = "'.tags_id[$i].'"

• 1-st level routes for multiple resources in Rails

  - by Leonid Shevtsov

  I have a simple SEO task. There's a City model and a Brand model, and I have to create 1st-level URLs for both (e.g. site.com/honda and site.com/boston). What's the preferred routing/controller combination to do this in Rails? I can only think of map.connect '/:id', :controller => 'catchall', :action => 'index' class CatchallController < ApplicationController def index if City.exists?(:slug => params[:id]) @city = City.find_by_slug!(params[:id]) render 'cities/show' else @brand = Brand.find_by_slug!(params[:id]) render 'brands/show' end end end but it seems to be very un-Rails to put such logic into the controller. (Obviously I need to make sure that the slugs don't overlap in the models, that's done).
