So in your case, if you just want to have CheckBoxes for your boolean fields, I wouldn't implement an own TableFieldFactory. Here's an example:</p> <pre><code>Table table = new Table(); table.addContainerProperty("text", String.class, ""); table.addContainerProperty("boolean", Boolean.class, false); table.setEditable(true); Object itemId = table.addItem(); table.getItem(itemId).getItemProperty("text").setValue("has accepted"); table.getItem(itemId).getItemProperty("boolean").setValue(true); </code></pre> <p>If you really need to have your own TableFieldFactory then Vaadin recommends:</p> <blockquote> <p>You could just implement the TableFieldFactory interface, but we recommend that you extend the DefaultFieldFactory according to your needs. In the default implementation, the mappings are defined in the createFieldByPropertyType() method (you might want to look at the source code) both for tables and forms.</p> </blockquote> <p>In your code given in the question you always return a TextField. For your missing CheckBoxes you need to return in the specific case a CheckBox.</p> <p>Don't forget to <code>setEditable(true)</code> when using FieldFactories.</p> <p>More information <a href="https://vaadin.com/book/-/page/components.table.html" rel="nofollow">here</a> under 5.16.3.

30,042,617 | 0 | <p>This is not possible using <a href="http://www.django-rest-framework.org/api-guide/filtering/#orderingfilter">the default <code>OrderingFilter</code></a>, because the ordering is implemented <em>on the database side</em>. This is for efficiency reasons, as manually sorting the results can be <em>incredibly</em> slow and means breaking from a standard <code>QuerySet</code>. By keeping everything as a <code>QuerySet</code>, you benefit from the built-in filtering provided by Django REST framework (which generally expects a <code>QuerySet</code>) and the built-in pagination (which can be slow without one).</p> <p>Now, you have two options in these cases: figure out how to retrieve your value on the database side, or try to minimize the performance hit you are going to have to take. Since the latter option is very implementation-specific, I'm going to skip it for now.</p> <p>In this case, you can use <a href="https://docs.djangoproject.com/en/1.8/ref/models/querysets/#id7">the <code>Count</code> function</a> provided by Django to do the count on the database side. This is provided as part of <a href="https://docs.djangoproject.com/en/1.8/topics/db/aggregation/">the aggregation API</a> and works like <a href="https://msdn.microsoft.com/en-us/library/ms175997.aspx">the SQL <code>COUNT</code> function</a>. You can do the equivalent <code>Count</code> call by modifying your <code>queryset</code> on the view to be</p> <pre><code>queryset = Topic.objects.annotate(vote_count=Count('topicvote_set')) </code></pre> <p>Replacing <code>topicvote_set</code> with <a href="https://docs.djangoproject.com/en/1.8/ref/models/fields/#django.db.models.ForeignKey.related_name">your <code>related_name</code> for the field</a> (you have one set, right?). This will allow you to order the results based on the number of votes, and even do filtering (if you want to) because it is available within the query itself.</p> <p>This would require making a slight change to your serializer, so it pulls from the new <code>vote_count</code> property available on objects.</p> <pre><code>class TopicSerializer(serializers.ModelSerializer): vote_count = serializers.IntegerField(read_only=True) class Meta: model = Topic </code></pre> <p>This will override your existing <code>vote_count</code> method, so you may want to rename the variable used when annotating (if you can't replace the old method).</p> <hr> <p>Also, you can pass a method name as the <code>source</code> of a Django REST framework field and it will automatically call it. So technically your current serializer could just be</p> <pre><code>class TopicSerializer(serializers.ModelSerializer): vote_count = serializers.IntegerField(read_only=True) class Meta: model = Topic </code></pre> <p>And it would work <em>exactly</em> like it currently does. Note that <code>read_only</code> is required in this case because a method is not the same as a property, so the value cannot be set.</p> |
40,333,042 | 0 | <p>Yes, you can send a <code>GET</code> request with no query string. In fact, whenever you hit a webpage using with your browser, you <em>are</em> sending a <code>GET</code> request, e.g. when you type <code>http://google.com</code> in the address bar and hit enter, your browser sends <code>GET</code> request to the URI and google server returns its page.</p> <p>As Mardzis noted in comments, you can use <code>empty()</code> function in your PHP code:</p> <pre><code><?php if (!empty($_GET['query'])) { $query = $_GET['query']; // Return results for specific query... } else { // Return all results... } </code></pre> <p><strong>EDIT</strong></p> <p>Since you've posted your Javascript code, I noticed something:</p> <pre><code>function showResults(str) { if (str.length == 0) { // If str is empty - isn't this where you want your "empty" query? But you don't } else { // If str is not empty, you send the request. } </code></pre> <p>Seems like if <code>str</code> is empty, you're not sending the request at all. Am I correct?</p> |

5,159,431 | 0 | Java reverse server communication <p>I have two machines. One machine is a client and the other is a server running JBoss. I have no trouble having the client make requests and the server respond to those requests. However, for a new project that I need to do I have to reverse the roles. I have to implement a push model, so the server will need to make requests from the client. Specifically I need the server to be able to ask the client for files in a directory, copy files from the server to the client, and run programs on the client. I'd like to do this without adding a psedo server on the client (a small daemon process).</p> <p>Is there a good way to do this?</p> <p>Thanks</p> <p>EDIT: So it would appear that I have to set up a server on the client machine to do what I need because I need to have the server push to the client while the client is not running the Java process (but the machine is on). With that in mind, what's the lightest weight Java server?</p> |

2,607,564 | 0 | <p>If you are simply geocoding cities, you may want to consider starting to build your own cities-to-coordinates cache.</p> <p>This is one approach that you may want to consider: </p> <ul> <li>Prompt the user to enter a city name.</li> <li>First issue an AJAX request to your server to check if that city name is present in your cache.</li> <li>If it is, proceed your JavaScript logic, as if you obtained the coordinates from the Google Geocoder.</li> <li>If the city name was not present in your cache, send a request to the Google Geocoder, as you are currently doing.</li> <li>If the Google Geocoder returns a positive result, issue another AJAX request to your server in order to store this city and its coordinates in your cache. You will never ask Google again for the coordinates of this city. Then proceed normally within your JavaScript application.</li> <li>If the Google Geocoder returns "Unknown address" tell the user that this city name was not found, and suggest to retry using a more common city name. Keep note of the original city name that was attempted. Test the second attempt with the Google Geocoder, and if it succeeds, save into your cache both synonyms of the city name (the first one attempted, and the second on that succeeded if not already present). </li> </ul> <p>With this approach you can also seed your cache, in such a way to resolve city names which you are already aware that Google is not able to geocode.</p> |
30,134,037 | 0 | <p>It finally worked. Thank you @Oleg! I saw another post here <a href="http://goo.gl/Pg5CMn" rel="nofollow">http://goo.gl/Pg5CMn</a></p> <p>Additionally, I figured that I was making another mistake. I forgot to enclose btnContactList in double quotes. After debugging in Internet explorer, I found that out. Secondly, as @Oleg suggested that the jsonReader attribute is required. Probably because of the version of jqGrid that I am using.</p> <pre><code><script type="text/javascript"> $(document).ready(function () { //alert("this is a test"); $("#btnContactList").click(function () { $("#ContactTable").jqGrid({ url: "/Contact/ContactList", datatype: "json", colNames: ["ID", "First Name", "Last Name", "EMail"], colModel: [ { name: "ContactId", index: "ContactId", width: 80 }, { name: "FirstName", index: "FirstName", width: 100 }, { name: "LastName", index: "LastName", width: 100 }, { name: "EMail", index: "EMail", width: 200 } ], //data: result, mtype: 'GET', loadonce: true, viewrecords: true, gridview: true, caption: "List Contact Details", emptyrecords: "No records to display", jsonReader: { repeatitems: false, //page: function () { return 1; }, root: function (obj) { return obj; }, //records: function (obj) { return obj.length; } }, loadComplete: function () { alert("Complete ok!") }, loadError: function (jqXHR, textStatus, errorThrown) { alert('HTTP status code: ' + jqXHR.status + '\n' + 'textstatus: ' + textstatus + '\n' + 'errorThrown: ' + errorThrown); alert('HTTP message body (jqXHR.responseText: ' + '\n' + jqXHR.responseText); } }); alert("after completion"); }); }); </script> </code></pre> |
