  • Why is $file empty in custom symfony file validator?

    - by codecowboy
    I am setting a custom file validator for a file input field in Symfony 1.4 (Doctrine) $this-setValidator('filename', new sfValidatorFile(array( 'mime_types' = 'web_images', 'path' = sfConfig::get('sf_upload_dir').'/animals', 'validated_file_class' = 'CustomValidatedFile', 'required' =false ))); I then want to override the save method to generate some thumbnails: class CustomValidatedFile extends sfValidatedFile { private $savedFilename; // Override sfValidatedFile's save method public function save($file = null, $fileMode = 0666, $create = true, $dirMode = 0777) { $this-savedFilename = $this-generateFilename(); // This makes sure we use only one savedFilename (it will be the first) if ($this-savedFilename === null ) { $this-savedFilename = $file; } $thumbnail = new sfThumbnail(150,150); $thumbnail-loadFile($this-getTempName()); $thumbnail-save(sfConfig::get('sf_upload_dir').'/thumbnails/thumb_'.$this-savedFilename); // Let the original save method do its magic :) return parent::save($this->savedFilename, $fileMode, $create, $dirMode); } } This fails with the error "The file "" is not readable." This is coming from sfThumbnailPlugin because the value of $file is null. My question is why is $file null?

  • Conditional value for ActiveRecord create method only

    - by Steve Wright
    I have a form where I have an administrator creating new users. The form uses the User model I created (login, password, first_name, etc...). For the last field on the form, I want to have a checkbox that doesn't need to be stored as part of the User record, but it is needed for the controller. This will control whether or not the newly created user will receive a welcome email or not. def create @user = User.new(params[:user]) if @user.save if @user.send_welcome_email UserMailer.welcome_email(@user).deliver end redirect_to(admin_users_url, :notice => "User #{@user.name} was successfully created.") else render :action => "new" end end In my view (haml) I am trying to access it like this: %p Send Welcome Email? = f.check_box :send_welcome_email I tried to make this an attr_accessible: :send_welcome_email but the controller does not recognize it. I get an undefined method 'send_welcome_email' for #&lt;User:0x00000100d080a8&gt; I would like it to look like this: What is the best way to get this working:

  • Getting a "summary" of a webpage

    - by MattiasK
    I have something of a a hairy problem, I'd like to generate a couple of paragraphs of "description" of a given url, normally the start of an article. The Meta description field is one way to go but it isn't always good or set properly. It's fair to say it's a bit problematic to accomplish this from the screenscraped HTML. I had a general idea that perhaps one could scan the HTML for the first "appropriate" segment but it's hard to say what that is, perhaps something like the first paragraph containing a certain amount of text... Anyone have any good ideas? :) It doesn't have to be foolproof

  • How can I remove a duplicate object from a MongoDB array?

    - by andrewrk
    My data looks like this: foo_list: [ { id: '98aa4987-d812-4aba-ac20-92d1079f87b2', name: 'Foo 1', slug: 'foo-1' }, { id: '98aa4987-d812-4aba-ac20-92d1079f87b2', name: 'Foo 1', slug: 'foo-1' } { id: '157569ec-abab-4bfb-b732-55e9c8f4a57d', name: 'Foo 3', slug: 'foo-3' } ] Where foo_list is a field in a model called Bar. Notice that the first and second objects in the array are complete duplicates. Aside from the obvious solution of switching to PostgresSQL, what MongoDB query can I run to remove duplicate entries from foo_list? Similar answers that do not quite cut it: http://stackoverflow.com/a/16907596/432 http://stackoverflow.com/a/18804460/432 These questions answer the question if the array had bare strings in it. However in my situation the array is filled with objects. I hope it is clear that I am not interested in a query; I want the duplicates to be gone from the database forever.

  • What is the fastest way to get the persisted object after calling Hibernate's saveOrUpdate?

    - by Dave
    I'm using Hibernate 3.2.1.ga, hibernate annotations 3.2.1.ga, and hibernate-jpa-2.0-api. I can't upgrade at this time as I'm working with legacy code. I have this generic method for saving or updating objects ... protected void saveOrUpdate(Object obj) { final Session session = sessionFactory.getCurrentSession(); session.saveOrUpdate(obj); } You can assume that every argument, "obj," will have a member field that is marked with the "@Id" annotation. I would like to change the return type to return an Object that represents the persisted object in the database (meaning if "obj" didn't contain an id before, what is returned is the database object with a populated id. What is the fastest way to do this given my versioning and generic constraints?

  • Database normalization and duplicate values

    - by bretddog
    Consider a Parent / Child / GrandChild structure in a database table schema, or even a deeper hierarchy. These being in the same aggregate. One table DAYS keeps a single row per day, and has a "Date" field. This is the root table, or maybe a child of the root. No row can ever be deleted in this table. In this case, however complex my table schema looks like, however far away in the hierarchy any other table is, is there any reason why any other table would hold a Date value? Can't it instead just have a FK to the DAYS table. I obviously assume that the creation of these date fields happen not before such datefield exist in the DAYS table. I'm now thinking just about the date part to be relevant, not the time part. Not sure if all databases can store these individually. That's maybe relevant, but not really the focus of the question.

  • Sorting in Matlab

    - by smichak
    Hi, I would like to sort elements in a comma-separated list. The elements in the list are structs and I would like the list to be sorted according to one of the fields in the struct. For example, given the following code: L = {struct('obs', [1 2 3 4], 'n', 4), struct('obs', [6 7 5 3], 'n', 2)}; I would want to have a way to sort L by the field 'n'. Matlab's sort function only works on matrices or arrays and on lists of strings (not even lists of numbers). Any ideas on how that may be achieved? Thanks, Micha

  • Drupal Event/Calendar Module not storing event time

    - by Selino
    Hello, all. I have installed a fresh copy of Drupal on an Xampp server. Within that install is a collection of modules for creating an event calendar. There's actually a great instructional video at http://www.youtube.com/watch?v=qO4TeEydtMs for getting all the necessary fields up. So far everything is working except... the events won't store the time as stated in the edit field. No matter what I do in the edit mode as admin or otherwise the time always says 12pm and the event on the calendar says "All Day". I know this is pretty obscure but I figured why not try and ask. Thanks.

  • Need help in downloading file with header() function

    - by riccardo
    Hi. I'm trying to explain as best as I can, sorry for my English. I have a list of links, each linked to a php file with an id by parameters (ex. download.php?id=1 or ?id=2 and so on). This file create a new instance of a class witch return the correct header of the files so it displays the save dialog box of the browser. Now I need to check if the files is already downloaded in past (The first time you downloaded it I add a field on the mysql db). This checks go ahead if you haven't download the files, else return false. Here is the problem, when it returns false or something else the browser redirect me to the download.php file, so I get a blank page or what I'm echoing. I need that if the file is already download it show me a js alert for advice ppl. Hope you can understand what i mean. Thanks for help

  • Is this query safe in SQL Server?

    - by xaw
    I have this SQL update query: UPDATE table1 SET table1.field1 = 1 WHERE table1.id NOT IN (SELECT table2.table1id FROM table2); Other portions of the application can add records to table2 which use the field table1id to reference table1. The goal here is to remove records from table1 which aren't referenced by table2. Does SQL Server automatically lock table2 with this kind of query so that a new record can't be added to table2 while executing this query? I've also considered: UPDATE table1 SET field1 = 1 WHERE 0 = (SELECT COUNT(*) FROM table2 WHERE table1.id = table2.table1id); Which seems possibly safer, but much slower (because a SELECT would be called on each row of table1 instead of just one select for the NOT IN)

  • efficient video format/codec for sparse & binary blob tracking

    - by user391339
    I am working on a blob tracking project and have many high-definition videos that I would like to reduce in size for storage and downstream tracking/shape-analysis. I want to use a lossless method that takes advantage of the black and white nature of the video as well as the fact that not much is moving between individual frames. The videos are quite sparse, with 5 to 10 b&w blobs per frame occupying <30% of the space in total, with each blob moving <5-10% of the field of view between frames and not changing shape too much between 2-3 frames. I will work in Python, Matlab, or LabView for this project, and could use a batch utility if available. It may be worthwhile to export the files as compressed image stacks if a proper video format can't be found. What are the pros and cons of this? A video codec uses correlations between neighboring frames, so it should be more efficient, but not if the wrong one is chosen or if it is improperly configured.

  • Where can I find "reference barcodes" to verify barcode library output?

    - by mjustin
    This question is not about 'best' barcode library recommendation, we use various products on different platforms, and need a simple way to verify if a given barcode is correct (according to its specification). There are some free online bar code generators in the Internet, and I found many differences between their output and our library output regarding graphics and text field below the code. Now I am not sure which one is wrong, and before filing bug report I want to make sure how the correct barcode should look like. We mainly need Code128 and UCC/EAN-128 with A/B/C subcodes. Which resource would you suggest?

    - by Dejan
    Hi all, I have a table field in MS Access 2003 which contains HTML encoded strings like this: &#913;&#957;&#964;&#945;&#947;&#969;&#957;&#953;&#963;&#956;&#972;&#962; &#960;&#945;&#947;&#954;&#959;&#963;&#956;&#943;&#959;&#965; &#949;&#960;&#953;&#960;&#941;&#948;&#959;&#965; &#963;&#964;&#951;&#957; &#954;&#945;&#964;&#940;&#961;&#964;&#953;&#963 How can I decode this into "normal string", using MS Access?

  • Extracting Data Daily from MySQL to a Local MySQL DB

    - by Sunny Juneja
    I'm doing some experiments locally that require some data from a production MySQL DB that I only have read access to. The schemas are nearly identical with the exception of the omission of one column. My goal is to write a script that I can run everyday that extracts the previous day's data and imports it into my local table. The part that I'm most confused about is how to download the data. I've seen names like mysqldump be tossed around but that seems a way to replicate the entire database. I would love to avoid using php seeing as I have no experience with it. I've been creating CSVs but I'm worried about having the data integrity (what if there is a comma in a field or a \n) as well as the size of the CSV (there are several hundred thousand rows per day).

  • Dojo Select widget validation style

    - by jamstooks
    Many dojo form widgets, like DateTextBox will style themselves in red (claro theme) with an "!" to indicate that the field isn't valid after focus. I can't seem to get this type of styling to work with the Select widget. I have the value set to required, but if the user leaves it in the default state, blank, then it remains unstyled. I tried to test this programmatically: wigs = dijit.findWidgets(node); for( i = 0; i < wigs.length; i++ ) { wigs[i].focus(); } This triggers validation on several other widgets and they are styled appropriately, but not he Select widgets. Anyone know how to make it obvious that those select widgets are not validating? Oh, and wigs[i].isValid() is definitely false for those select widgets.

  • In C, is it possible do free only an array first or last position?

    - by user354959
    Hi there! I've an array, but I don't need its first (or last) position. So I point a new variable to the rest of the array, but I should free the array first/last position. For instance: p = read_csv_file(); q = p + 1; // I don't need the first CSV file field // Here I'd like to free only the first position of p return q; Otherwise I've to memcpy the array to other variable, excluding the first position, and then free the original array. Like this: p = read_csv_file(); q = (int*) malloc(sizeof(int) * (SOME_SIZE - 1)); memcpy(q, p+1, sizeof(int) * (SOME_SIZE - 1)); free(p); return q; But then I'll have the overhead of copying all the array. Is this possible to only free a single position of an array?

  • Access outer class from inner class: Why is it done this way?

    - by Vuntic
    So most of us know how to access an outer class from an inner class. Searches with those words give oodles of answered questions on that topic. But what I want to know is why the syntax is the way it is. Example: public class A { private class B { public void c() {A.this.d();} } public void d() {System.out.println("You've called d()! Go, you!");} } Why is it A.this.d()? It looks like this is a static field of class A, but... * am confused * Forgive me if this is a repeat; like I said, searches with those words give how-answers.

  • Two Different Types of Associatons on the Same Two Tables in Rails

    - by tmo256
    I have two models, users and themes, that I'm currently joining in a HABTM association in a themes_users table. Basically, after a user creates a new theme, it becomes available to other users to select for their own use. However, only the original creator of the theme should have the ability to edit it. So, I need to have some other kind of association to handle that relationship, something like an created_by_id field in the theme. In this way, the user model acts as two different roles: they can be an implementer of a theme AND/OR the owner of the theme. The implementer relationship is handled by the themes_users join table; the question is: What is the right way to handle this secondary association? Do I need to make users polymorphic and then make the created_by_id reference an "owner"? Or is there something easier? Thanks so much for your help!

  • How not to lose focus on a login page

    - by Misha Moroshko
    I have a simple login form with 2 input fields: "username" and "password". "username" field is focused by default. The problem is that when user clicks outside "username" or "password" fields, the focus is gone (it is neither on "username" nor on "password" fields"). How can I force the focus to be on these 2 fields only ? In my case, this is a really annoying behavior, so I really want to do this :) Can I do something like: $("*").focus(function() { if (!$(this).hasClass("my_inputs_class")) { // How to stop the focusing process here ? } }); ?

  • C++ Singleton design pattern.

    - by Artem Barger
    Recently I've bumped into realization/implementation of Singleton design pattern for C++. It has looked in the following way (I have adopted it from real life example): // a lot of methods is omitted here class Singleton { public: static Singleton* getInstance( ); ~Singleton( ); private: Singleton( ); static Singleton* instance; }; From this declaration I can deduce that instance field is initiated on the heap, that means there is a memory allocation. That is completely unclear for me is when does exactly memory is going to be deallocated? Or there is a bug and memory leak? It seems like there is a problem in implementation. PS. And main question how to implement it in the right way?
