  • Stop output of image if no record - paperclip - Ruby on rails

    - by bgadoci
    I have just installed paperclip into my ruby on rails blog application. Everything is working great...too great. I am trying to figure out how to tell paperclip not to output anything if there is no record in the table so that I don't have broken image links everywhere. How, and where, do I do this? Here is my code: class Post < ActiveRecord::Base has_attached_file :photo, :styles => { :small => "150x150"} validates_presence_of :body, :title has_many :comments, :dependent => :destroy has_many :tags, :dependent => :destroy has_many :ugtags, :dependent => :destroy has_many :votes, :dependent => :destroy belongs_to :user after_create :self_vote def self_vote # I am assuming you have a user_id field in `posts` and `votes` table. self.votes.create(:user => self.user) end cattr_reader :per_page @@per_page = 10 end View <% div_for post do %> <div id="post-wrapper"> <div id="post-photo"> <%= image_tag post.photo.url(:small) %> </div> <h2><%= link_to_unless_current h(post.title), post %></h2> <div class="light-color"> <i>Posted <%= time_ago_in_words(post.created_at) %></i> ago </div> <%= simple_format truncate(post.body, :length => 600) %> <div id="post-options"> <%= link_to "Read More >>", post %> | <%= link_to "Comments (#{post.comments.count})", post %> | <%= link_to "Strings (#{post.tags.count})", post %> | <%= link_to "Contributions (#{post.ugtags.count})", post %> | <%= link_to "Likes (#{post.votes.count})", post %> </div> </div> <% end %>

  • What is the correct way to reference RDFa namespaces in HTML5?

    - by Eivind Eidheim Elseth
    I'm setting up a HTML5 webpage and want to include RDFa. I try checking the syntax with the w3 validator, and check the extracted RDF using the w3 RDFa distiller. When I declare namespaces using xmlns:<ns>="<uri>" the validator complains that the attribute is not allowed there, and the specs say that xmlns is deprecated, but if I try the other suggested prefix="<ns> <uri>" the distiller doesn't discover the RDFa embedded on my page. Which way should I stick to?

  • Managing important runtime business logic with regard to a codebase

    - by Daniel Beardsley
    I'm working on a project which will end up have a lot of application information stored in the form of records in a database. In this case, it's the configuration of data views: which grid columns to show/hide default filters to apply to each grid view column titles sorting subtotaling ... This information is a big part of the value of the application and is essential to it's function. The data will be altered by admins a fair amount, so it's not static and it wouldn't be appropriate to have to deploy a new version of the app every time the data changes. The question is, Where should this data be stored? It will definitely live in the database because that's how it's accessed, but I feel like it needs to also be kept with the version controlled codebase because it's an integral part of functioning of the application. Has anyone dealt with an issue like this before? What did you end up doing?

  • Why do WCF clients depend on the app.config file?

    - by routeNpingme
    Like a lot of things, I'm sure there's a good reason for this, so please help me understand... Why, by default, do WCF services store settings in app.config? This has been so frustrating trying to work with multiple Silverlight class libraries. These class libraries are supposed to be completely independent from each other, and this dependency on the app.config seems to cause the following headaches: Single Responsibility Principle - I should be able to add a reference to a class library and go. If that class library uses a service reference, this idea is shot before I even start coding against it. Muddy Configuration - To get other libraries to work, I have to copy and paste the service configurations into the "main" application configs. If an endpoint changes in any way, I can't just worry about a new version of that class DLL - I have to worry about anything that uses it, too. Complex Alternatives - Programmatically creating the endpoint isn't pretty. Period. There has to be a better way. Why doesn't WCF at least separate the service configurations into a ServiceName.config or something that gets copied to an output directory. What am I missing? How do you deal with this?

  • Should I stick only to AWS RDS Automated Backup or DB Snapshots?

    - by James Wise
    I am using AWS RDS for MySQL. With it comes on backup, I understand that amazon provides two types of backup - automated backup and database (DB) snapshot. The difference is explain in here - http://aws.amazon.com/rds/faqs/#23. However, I am still confuse if should I stick to automated backup only or both automated and manual (db snapshots). What do you think guys? What's the setup of your own? I heard to others that automated backup is not reliable due to some unrecoverable database when the DB instance is crashed so the DB snapshots are the way to rescue you. If I will do daily DB snapshots as similar settings to automated backup, I have gonna pay much bunch of bucks. Hope anyone could enlighten me or advise me the right set up. Thanks. James

  • Folders-like URL with PHP?

    - by Maxime
    Hi, ever since I added this htaccess to my website, I noticed a HUGE slowdown, and my error logs are filled with errors such as PHP Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in page.php on line 79. I've got up to four of these per second. Most of the time it works though. The htaccess consisted of two similar rules: one with two GET vars, another one with only one. RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)\/(.*)$ index.php?var1=$1&var2=$2 [L] Anyway, I just rewrote a PHP script that handles of all the strings and redirects where it should, and my website is now fast again. But is there a way to hide mypage.php?var1=la&var2=lu and still have URLs that look like folders? Thanks for your replies!

  • ASP.NET MVC Actions that return different views, or just make a ton of Actions?

    - by Nate Bross
    So, I am in a situation, where I need to display a different view based on the "Role" that the authenticated user has. I'm wondering which approach is best here: [Authorize(Roles="Admin")] public ActionResult AdminList(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); return View(data); } [Authorize(Roles = "Consultant")] public ActionResult ConsultantList(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); return View(data); } or should I do something like this [Authorize] public ActionResult List(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); if(HttpContenxt.User.IsInRole("Admin") { return View("AdminList", data ); } if(HttpContenxt.User.IsInRole("Consultant") { return View("ConsultantList", data ); } return View("NotFound"); }

  • Post complex types to WebApi Client

    - by BumbleBee
    I am new to WebAPI. I have a MVC project and webApi project both reside under the **same solution**. Also, BLL Class library and DAL class library reside under the same solution. Earlier, my MVC project will talk to the BLL now I am trying to create a WebAPi project which stands in between MVC and BLL. Here is what I have come up with so far : I'm using the HTTPClient to post to a WebApi project. My post method on my controller accepts a single parameter (a model). StatsCriteria criteria = new StatsCriteria(); ...... var client = new HttpClient(); var response = client.PostAsJsonAsync("http://localhost:52765/api/reports", criteria).Result; ....... Here's the signature for my controller in Webapi [HttpPost] public CMAReportVM Reports([FromBody] StatsCriteria criteria) { var cmaReport = Service3.GetCMAReport(criteria.Mlsnums); //Create Map to enable mapping business object to View Model Mapper.CreateMap<CMAReport, CMAReportVM>(); // Maps model to VM model class var cmaVM = Mapper.Map<CMAReport, CMAReportVM>(cmaReport); reutn cmaVM; } // and here's my routing: config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } I am getting the following 405 : Method not allowed. As the WebAPI and MVC project both reside under same sloution I am not sure where/how to host my webapi.

  • Website. AJAX and FIREFOX problems. I dont think Firefox likes ajax..?

    - by DJDonaL3000
    Working on an AJAX website (HTML,CSS,JavaScript, AJAX, PHP, MySQL). I have multiple javascript functions which take rows from mysql, wrap them in html tags, and embed them in the HTML (the usual usage of AJAX). THE PROBLEM: Everything is working perfect, except when I run the site with Firefox (for once its not InternetExplorer causing the trouble). The site is currently in the developmental stage, so its offline, but running on the localhost (WampServer, apache, Windows XP SP3,VISTA,7). All other cross-browser conflicts have been removed, and works perfectly on all major browsers including IE, Chrome, Opera and Safari, but I get absolutely nothing from the HTTPRequest (AJAX) if the browser is Firefox. All browsers have the latest versions. THE CODE: I have a series of javascript functions, all of which are structured as follows: function getDatay(){ var a = document.getElementById( 'item' ).innerHTML; var ajaxRequest; try{//Browser Support Code: // code for IE7+, Firefox, Chrome, Opera, Safari: ajaxRequest = new XMLHttpRequest(); } catch (e){ // code for IE6, IE5: try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Your browser is not compatible - Browser Incompatibility Issue."); return false; } } } // Create a function that will receive data sent from the server ajaxRequest.onreadystatechange = function(){ if(ajaxRequest.readyState < 4){ document.getElementById( 'theDiv' ).innerHTML = 'LOADING...'; } if(ajaxRequest.readyState == 4){ document.getElementById( 'theDiv' ).innerHTML = ajaxRequest.responseText; } } //Post vars to PHP Script and wait for response: var url="01_retrieve_data_7.php"; url=url+"?a="+a; ajaxRequest.open("POST", url, false);//must be false here to wait for ajaxRequest to complete. ajaxRequest.send(null); } My money is on the final five lines of code being the cause of the problem. Any suggestions how to get Firefox and AJAX working together are most welcome...

  • Flipping around a div using Javascript

    - by Isaac Copper
    Flip is a great JQuery plugin for flipping blocks, but it doesn't preserve the background while it animates the flip. For example, I have this pretty background, here, before I flip. While flipping, it gets ugly: here. Is there a way I can flip this div nicely, keeping the pretty background I have, and maybe even achieve a smoother animation than I can get with Flip? If I need to dive into this headfirst and code my own function for flipping a div, that's also doable, and I'd really appreciate some pointer there, if that's what I must do. Thanks so much!

  • setting cookies

    - by aharon
    Okay, so I'm trying to set cookies using Ruby. I'm in a Rack environment. response[name]=value will add an HTTP header into the HTTP headers hash rack has. I know that it works. The following method doesn't work: def set_cookie(opts={}) args = { :name => nil, :value => nil, :expires => Time.now+314, :path => '/', :domain => Cambium.uri #contains the IP address of the dev server this is running on }.merge(opts) raise ArgumentError, ":name and :value are mandatory" if args[:name].nil? or args[:value].nil? response['Set-Cookie']="#{args[:name]}=#{args[:value]}; expires=#{args[:expires].clone.gmtime.strftime("%a, %d-%b-%Y %H:%M:%S GMT")}; path=#{args[:path]}; domain=#{args[:domain]}" end Why not? And how can I solve it? Thanks.

  • PHP - JSON Steam API query

    - by Hunter
    First time using "JSON" and I've just been working away at my dissertation and I'm integrating a few features from the steam API.. now I'm a little bit confused as to how to create arrays. function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530'); $test = decode_url($api); var_dump($test['response']['players'][0]['personaname']['steamid']); } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $data = file_get_contents($url); $data_output = json_decode($data, true); return $data_output; } So ea I've wrote a simple method to decode Json as I'll be doing a fair bit.. But just wondering the best way to print out arrays.. I can't for the life of me get it to print more than 1 element without it retunring an error e.g. Warning: Illegal string offset 'steamid' in /opt/lampp/htdocs/lan/lan-includes/scripts/class.steam.php on line 48 string(1) "R" So I can print one element, and if I add another it returns errors. EDIT -- Thanks for help, So this was my solution: function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530,76561197960435530'); $data = decode_url($api); foreach($data ['response']['players'] as $player) { echo "Steam id:" . $player['steamid'] . "\n"; echo "Community visibility :" . $player['communityvisibilitystate'] . "\n"; echo "Player profile" . $player['profileurl'] ."\n"; } } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $json = file_get_contents($decodeURL); $data_output = json_decode($json, true); return $data_output; } Worked this out by taking a look at the data.. and a couple json examples, this returns an array based on the Steam API URL (It works for multiple queries.... just FYI) and you can insert loops inside for items etc.. (if anyone searches for this).

  • AWS Load Balancer with a static IP address

    - by user965904
    I have a set-up running on Amazon cloud with a couple of EC2 Instances running through a load balancer. It is important that the site has a unique(static) IP or set of IPs as I'm plugging in 3rd party APIs which only accept requests made from IPs which have been added to their whitelist. So basically unless we can give these 3rd parties a static IP or range of IPs that the requests from the site will always come from then we would be unable to make any calls to them. Anyone knows how to achieve this as I know that Elastic IPs are not compatible with load balancers? If I were to look up the IP of the load balancer DNS name (e.g. dualstack.awseb-BAMobile-ENV-xxxxxxxxx.eu-west-1.elb.amazonaws.com resolves to 200.200.200.200) would that IP be Static? Any help/advise is greatly appreciated guys.

  • Web Hosting: Any web host that supports files more than 50,000 in number?

    - by Devner
    Hi all, For my PHP & mySQL based application, I am trying to buy website hosting from a host who does not have a limit on the number of files I carry in my hosting account. Almost all the websites have a common limit of 50,000 files (some websites call it 50,000 nodes). The rest(to the extent of my search) are not even close. I have gone through the various websites, Googled lot of information, have spoken with the customer service of the hosting companies and they said that they have a limit of 50,000 files and that's why they call it the LIMIT. Now I have my application, which is a kind of social networking website, where people can upload various files of varying file size. So say if 50,000 users were to join the website and upload 1 file each, the limit of 50,000 will be reached very easily and my 50,001 customer will start facing file upload problems (& so will my account). So I would like to know if there's any website hosting services that do NOT levy such restrictions. In summary, I need the following options: No maximum file limit (more than 50,000 files in account). No maximum file upload limit in server setting (10MB, 12MB, 15MB, 20MB, etc.). Ability to upload files of various types (zip, flv, jg, png, etc.). Ability to stream Audio and Video (live audio & video not necessary). Access to .htaccess Access to php.ini, my.cnf or my.ini (this would be a plus) Supports SSL. Provides dedicated hosting(& IP) as well. Monthly payments without contracts are a plus. If you know of any such website hosting services, please post a reply ( a link to the same will be appreciated ). Thank you.
