  • Gson serialization depending on field value

    - by Serj Lotutovici
    I have a POJO that is similar to: public class MyGsonPojo { @Expose @SerializedName("value1") private String valueOne; @Expose @SerializedName("value2") private boolean valueTwo; @Expose @SerializedName("value3") private int valueThree; // Getters and other stuff here } The issue is that this object has to be serialized into a json body for a call to the server. Some fields are optional for the request and if I even send it with default and null values, the API responds differently (Unfortunately changing the api is not an option). So basically I need to exclude fields from serialization if any of them is set to a default value. For example if the field valueOne is null the resulting json should be: { "value2" : true, "value3" : 2 } Any idea how to make this a painless effort? I wouldn't want to build the json body manually. Any help would be great. Thank you in advice.

  • Fastest/One-liner way to list attr_accessors in Ruby?

    - by viatropos
    What's the shortest, one-liner way to list all methods defined with attr_accessor? I would like to make it so, if I have a class MyBaseClass, anything that extends that, I can get the attr_accessor's defined in the subclasses. Something like this: class MyBaseClass < Hash def attributes # ?? end end class SubClass < MyBaseClass attr_accessor :id, :title, :body end puts SubClass.new.attributes.inspect #=> [id, title, body] What about to display just the attr_reader and attr_writer definitions?

    - by wangjl1110
    friends. I'm currently developing a flex mobile project. I currently need to load local javascript using stagewebview. Like: var str:String = '<head>'+ '<script src="myLocalJs.js"/>'+ '</head><body>...</body>'; webView:StageWebView = new StageWebView(); webView.loadString(str); Is there any way to load local javascript using StageWebView? I'm not expecting an answer like 'There is a project called StageWebViewBridge' since it does't have all the features I need. THX!!

  • Joomla contact form doesn't pass W3C validation

    - by aramaz
    Hi, I get the following error when I try to validate a contact page on my site: document type does not allow element "script" here The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed). One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error). I am using Joomla 1.5.7, and the doctype is <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Any idea how to fix this?

  • how does teamviewer find my computer even if my comp. behind of the firewall and firewall isn't conf

    - by uzay95
    Did you use teamviewer? (comic question i know... Who doesn't use it?) Do you have any idea how does teamviewer make connection even if i am behind the router, firewall, switch and my local firewall..? I'm trying to imagine a connection that is between remote machinge and my computer. Remote machine is sending the packets (and its header (for instance, destination IP, message body)) to me but it only knows my id number(which is given by my local teamviewer application). And this packets are reaching to my computer even if there is a juniper firewall (and also my windows firewall). What kind a message body is recieving by computer? (of course it is not like xml, text, html, excel :) Do you have any idea? PS. Please share your knowledge like you are explaining to beginner level user.

  • Interface name as a Type

    - by user1889148
    I am trying to understand interfaces in Java and have this task to do which I am a stack with. It must be something easy, but I don't seem to see the solution. Interface contains a few methods, one of them should return true if all elements of this set are also in the set. I.e. public interface ISet{ //some methods boolean isSubsetOf(ISet x); } Then the class: public class myClass implements ISet{ ArrayList<Integer> mySet; public myClass{ mySet = new ArrayList<Integer>(); } //some methods public boolean isSubsetOf(ISet x){ //method body } } What do I need to write in method body? How do I check that the instance of myClass is a subset of ISet collection? I was trying to cast, but it gives an error: ArrayList<Integer> param = (ArrayList<Integer>)x; return param.containsAll(mySet);

  • Using Python simplejson for transmitting JSON to another server results in unicode encoding problems

    - by Mark
    Hi there, I'm encoding a string with Python's simplejson library with special characters: hello testing spécißl characters plusses: +++++ special chars :œ?´®†¥¨ˆøp“ß?ƒ©??°¬O˜çv?˜µ== However, when I encode it and transmit it to the other machine (using POST), it turns out like this: {'message': ['{"body": "hello testing sp\\u00e9ci\\u00dfl characters\\n\\nplusses: \\n\\nspecial chars :\\u0153\\u2211\\u00b4\\u00ae\\u2020\\u00a5\\u00a8\\u02c6\\u00f8\\u03c0\\u201c\\u00df\\u2202\\u0192\\u00a9\\u02d9\\u2206\\u02da\\u00ac\\u03a9\\u2248\\u00e7\\u221a\\u222b\\u02dc\\u00b5\\u2264\\u2265"}']} The + signs are completely stripped and the rest are in this unicode(?) format. My code for this is: data = {'body': data_string} data_encoded = json.dumps(data) Any ideas? Thanks! Edit: I've tried using json.dumps(data, ensure_ascii=False) but it results in a UnicodeError ordinal not in range error.

    I'm pulling a lot of text from a MS SQL Server database. I'm not getting all the text (which includes some html. The text is stored perfectly on the database. However, when I run the query to get the data It will only pull part of the text.

Is there a size limit? Any ideas what I'm missing here?

  • How do i get access to the <html> element in javascript?

    - by kwyjibo
    IE displays a default scrollbar on the page, which appears even if the content is too short to require a scrollbar. The typical way to remove this scrollbar (if not needed), is to add this to your css: HTML { height: 100%; overflow: auto; } I'm trying to do the same thing in javascript (without requiring that in my CSS), but i can't seem to find a way to get access to the html element. I know i can access the body element with document.body, but that doesn't seem to be sufficient, i need the wrapping html element. Any tips?

The messages are being sent from valid email addresses. What would be causing our our servers to label it as junk? MailMessage msg = new MailMessage(); msg.IsBodyHtml = true; msg.Subject = subject; msg.Body = body; msg.From = new MailAddress(from); msg.To.Add(to); SmtpClient client = new SmtpClient(server, 25); client.Send(msg);
