  • App Engine datastore does not support operator OR

    - by JohnIdol
    I am trying to query the google datastore for something like (with pm -- persistanceManager): String filters = "( field == 'value' || field == 'anotherValue' )"; Query query = pm.newQuery(myType.class, filters); When I execute - I am getting back: App Engine datastore does not support operator OR. What's the best approach in people experience for this kind of queries? Any help appreciated!

  • Google maps api v3 refreshing away markers

    - by Paul Peelen
    Hi, I am having problems with the google maps API V3. It seems that every time I load my page the maps load (including the markers) and then it does a quick reload and removes all the markers. Am I missing somehting? What am I doing wrong? Here is an example: http://www.PaulPeelen.com/wp-content/uploads/2010/04/SafariScreenSnapz001.mov this is my code: <script type="text/javascript"> <!-- var hash = "{{$sHashLocal}}"; var webroot = "{{$webroot}}"; var map; function initialize() { var latlng = new google.maps.LatLng(59.32045, 18.066902); var myOptions = { zoom: 13, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); return map; } function getMarkerInfo (infowindow, rack_id) { // Get all the racks $.ajax({ type: "GET", url: webroot+"ajax/getRack/"+hash+"/"+rack_id, cache: false, dataType: "html", success: function(html) { $("#rack_"+rack_id).html(); infowindow.setContent(html); } }); } $(document).ready(function () { map = initialize(); function attachSecretMessage(marker, rack_id) { var infowindow = new google.maps.InfoWindow({ size: new google.maps.Size(50,50) }); google.maps.event.addListener(marker, 'click', function(){ var ret = '<div id="rack_'+rack_id+'" class="rackDiv"><div class="rackDivLoading"><img src="theme/images/loader-small.gif" border="0"/><span>Hämtar data</span></div></div>'; infowindow.setContent(ret); infowindow.open(map,marker); getMarkerInfo(infowindow,rack_id); }); } function addPlacemark (lat,lng,title, rack_id) { var image = new google.maps.MarkerImage('http://www.google.com/intl/en_us/mapfiles/ms/micons/blue-dot.png', new google.maps.Size(32, 32), new google.maps.Point(0,0), new google.maps.Point(0, 32)); var shadow = new google.maps.MarkerImage('http://maps.google.com/mapfiles/shadow50.png', new google.maps.Size(37, 34), new google.maps.Point(0,0), new google.maps.Point(-4, 34)); var location = new google.maps.LatLng(lat,lng); var marker = new google.maps.Marker({ position: location, map: map, icon: image, shadow: shadow}); marker.setTitle(title); attachSecretMessage(marker, rack_id); } // Get all the racks $.ajax({ type: "GET", url: webroot+"ajax/getRacks/"+hash, cache: false, dataType: "xml", success: function(xml) { // Add the results $(xml).find("station").each(function () { rack_id = $(this).find("rack_id").text(); title = $(this).find("description").text(); longitute = parseFloat($(this).find("longitute").text()); latitude = parseFloat($(this).find("latitude").text()); addPlacemark(latitude, longitute, title, rack_id); }); } }); $("#addMark").click(function () { addPlacemark (59.32045, 18.066902); }); // Set size setPageSize(); }); //--> </script> I hope somebody can help me.

  • Create a Search Filter List in Google Chrome

    - by Asian Angel
    Are you tired of unwanted and/or non-relevant results cluttering up the search results at Bing, Yahoo, and Google? With the Search Filter extension for Chrome you can easily remove the unwanted “chaff” from your search results. Note: The extension only works on Bing, Yahoo, and Google at this time. Before For our example we conducted a search for “anime wallpapers” at Yahoo Singapore, Bing Singapore, and Google. In each set of results we decided to focus on results that would display either a yellow or red warning color from WOT. You can see our targeted result for Yahoo Singapore… The one for Bing Singapore… And the targeted result from Google. Search Filter in Action As soon as you install the extension you should take a quick look at the “Options”. At first the “Filters List Area” will be empty but will not remain so for long as you create your own filter list. The second part may or may not be of interest to you…the ability to opt into the filter service. If you opt in your filter list will be connected to your “Google Account” and will be available on any of your Chrome installs with the extension installed (and set to “Opt In”). Keep in mind that if you choose this option the filter list that you create will be aggregated anonymously and have a GUID number attached to it. After installing the extension we refreshed each of our three search pages…notice the small red circle button beside each search result link. Clicking on the red circle button will cause the entire browser window area to “shade out” temporarily while you decide between adding that website to the filter list or cancelling the action. If you add a website to the filter list that result will immediately disappear from the search results list without refreshing the webpage. Looks like we have another website at the bottom that we could add to the filter list… Click, click, click! After adding one website from each of the three search services you can see that our filter list has gotten off to a nice start. If for some reason you accidentally add a website to the list or change your mind about a website simply click on the red circle button to remove that particular listing. Conclusion If you are looking for an easy way to create a search filter list then this is definitely an extension that is worth taking the time to look at.

  • Enable Multi-Column Google Searches with a User Script

    - by Asian Angel
    Are you wanting to improve the search results view at Google and make better use of the webpage space? With a little user script magic you can make those search results look and fit better in your favorite browser. Note: This user script may conflict with the AutoPager extension if you have it installed in your favorite browser. Before Here is the standard single column view of search results at Google. Not too bad but the available space could certainly be better utilized. Note: For the purposes of our example we are using Google Chrome but this user script can be easily added to other browsers. After If you have never installed a user script in Chrome before it is just as simple as the regular extensions at the official Google website. Here you can see the details for the user script we are installing. Notice that you can view the source code if desired. To add the user script to Chrome click on “Install”. Once you start the install process you will see an intermediary message asking if you wish to continue in the lower left corner of your browser. Click “Continue” to move to the next step in the install process. From this point on the install process is practically identical to the official extensions. You can see the final confirmation window here…click “Install” to finish adding the user script to Chrome. As with regular extensions you will see a post-install message in the upper right corner. So, what does a user script look like in the “Extensions Page”? You can see the user script entry here…outside of an icon it looks rather identical to a normal extension. After refreshing the search page shown above we now have two columns of search results (default setting). This looks much much better than a single column view and there is little to no page scrolling required now. To switch to a three column view simply use the keyboard shortcut “Alt + 3”. To return to a single column view use “Alt + 1” and for the default two column view use “Alt + 2”. Three keyboard shortcuts for three different views…definitely a good thing. Note: On our test system we needed to use the number keys at the top of our keyboard to switch views…this is most likely the result of unique settings on our test system. Conclusion If you are wanting a better viewing experience when conducting searches at Google then this user script will make a very nice addition to your favorite browser. For those using Firefox you can add user scripts with the Greasemonkey & Stylish extensions. Using Opera Browser? See our how-to for adding user scripts to Opera here.

  • Google Analytics on Static Site Hosted by GAE

    - by Cody Hess
    I finagled hosting a static site on Google App Engine at http://corbyhaas.com The HTML when visiting the URL shows some meta information and a frame to the site's actual address: http://cody-static-sites.appspot.com/corbyhaas which has the content. This is done automagically by Google App Engine. I've set up Google Analytics by including their script in my index.html, but the report shows 100% of visits coming from referring site "corbyhaas.com", which is useless information. Has anyone set up Google Analytics for a static GAE site? Is there a setting in my Analytics dashboard I can tweak, or is this a hazard of using Google App Engine for static content? Also, while it's not relevant here (but could be for future sites), does GAE's method of showing only meta information with frames for static data affect SEO?

    - by Akemi Iwaya
    Are you someone who loves using Google Chrome or ChromeOS, but have been frustrated by the lack of parental controls? Then this bit of news will definitely cheer you up! Google has introduced a new supervised users feature into the beta channels of Chrome and ChromeOS that will help you lock your browser or system down and better protect your children.

  • HTML 5, Fluid Pages and Google Mobile Index

    - by Bob
    I am currently migrating my site to HTML5, at the same time designing pages so that they are "fluid" and are equally presentable for a mobile or a large screen. I took the fluid approach so as not to have to develop a separate application for mobile devices and I'm pleasantly surprised with the results that look equally as good on an iPhone as they do on a large screen. Then I went into the Google Webmaster Tools facility and became aware of the Google Mobile Index. I'm confused now as HTML5 doesn't seem to be supported by Google Mobile Indexing. Does this mean that when I go live with my new "pride and joy" HTML5 site on a mobile it won't appear on any Google searches as it's not in the Google Mobile Index?

  • Pointing domain away from google

    - by redbeard
    I've already asked this question on google apps support, didnt fet an answer yet, and I am in a bit of a hurry. Need to have that website up by monday. Question: We have a domain registered at 101domain, we used a domain just for google apps, for email, and some services, and domain was never used for website. Now we pointed domain to the local hosting service, set everything like it should be, and pointed back to google from hosting service for gmail and gmail works perfectly. Problem is that we tried to set up a website at hosting service but domain still points to google apps login. Everything looks like it should, we recently bought 2 more domains that are set up the same (we use google apps on them too), the only difference tha I can think of is that we didn't use for apps first. Could this be because CNAME lags behind DNS server change?

  • Does the Instant Preview in Google webmaster tools takes Robot.txt in account?

    - by rockyraw
    Is that the way to go If I want to visually see what the googlebot see? I'm trying to check a folder which I have just blocked in my robots.txt. If I fetch the folder as google bot, It fetches ok, so that doesn't tell me nothing about whether the block is working I know there's a tool to check for blocking, but it is dependent on the input of the robots.txt Therefore I've tried the Instant preview, and I don't get a preview for what the bot sees ("pre-render), so I think that means that it's because the robots.txt blocks it; however - I don't see the bot tried beforehand to access my updated robots.txt, so I'm not sure how does it know that this folder is blocked? (it does preview another new folder, that is not blocked)

  • Appengine datastore phantom entity - inconsistent state?

    - by aloo
    Getting a weird error on java appengine code that used to work fine (nothing has changed but the data in the datastore). I'm trying to iterate over the results of a query and change a few properties of the entities. The query does return a set of results, however, when I try to access the first result in the list, it throws an exception when trying to access any of its properties (but its key). Here's the exception: org.datanucleus.state.JDOStateManagerImpl isLoaded: Exception thrown by StateManager.isLoaded Could not retrieve entity of kind OnTheCan with key OnTheCan(3204258) org.datanucleus.exceptions.NucleusObjectNotFoundException: Could not retrieve entity of kind OnTheCan with key OnTheCan(3204258) at org.datanucleus.store.appengine.DatastoreExceptionTranslator.wrapEntityNotFoundException(DatastoreExceptionTranslator.java:60) And here is my code: PersistenceManager pm = PMF.get().getPersistenceManager(); Query query = null; List<OnTheCan> cans; query = pm.newQuery("SELECT this FROM " + OnTheCan.class.getName() + " WHERE open == true ORDER BY onTheCanId ASC"); query.setRange(0, num); cans = (List<OnTheCan>) query.execute(); for (OnTheCan c : cans) { System.err.println(c.getOnTheCanId()); // this works fine! getting the key works c.setOpen(false); // failure here with the above exception c.setAutoClosed(true); c.setEndTime(new Date(c.getStartTime().getTime() + 600000/*10*60*1000*/)); } pm.close(); The code throws the exception when trying to execute c.setOpen(false) - thats the first time I'm accessing or setting a property that isnt the key. So it seems there is a phantom entity in my datastore with key 3204258. THis entity doesn't really exist (queried the datastore from admin console) but for some reason its being returned by the query. Could my data store be in an inconsistent state? I've managed the following workaround by placing it as the first line in my for loop. Clearly an ugly hack: if (c.getOnTheCanId() == 3204258) { continue; } Any ideas?

  • Copy an entity in Google App Engine datastore in Python without knowing property names at 'compile'

    - by Gordon Worley
    In a Python Google App Engine app I'm writing, I have an entity stored in the datastore that I need to retrieve, make an exact copy of it (with the exception of the key), and then put this entity back in. How should I do this? In particular, are there any caveats or tricks I need to be aware of when doing this so that I get a copy of the sort I expect and not something else. ETA: Well, I tried it out and I did run into problems. I would like to make my copy in such a way that I don't have to know the names of the properties when I write the code. My thinking was to do this: #theThing = a particular entity we pull from the datastore with model Thing copyThing = Thing(user = user) for thingProperty in theThing.properties(): copyThing.__setattr__(thingProperty[0], thingProperty[1]) This executes without any errors... until I try to pull copyThing from the datastore, at which point I discover that all of the properties are set to None (with the exception of the user and key, obviously). So clearly this code is doing something, since it's replacing the defaults with None (all of the properties have a default value set), but not at all what I want. Suggestions?

  • Google tweets – Now search twitter archives using Google

    - by samsudeen
    Google has launched a Twitter archive service which allows you to  search tweets in real time as well as on its huge public archive (remember Twitter crossed 10 billionth tweet last month). The search results are displayed as tweets with twitter logo. To explore the twitter search go to Google.com homepage  and select   “Show options” on the search results page, then select “Updates.”.  The search is similar to the Google search with options to dig through the tweets by timeframe. You can explore results by zooming through a particular time range  or date. In addition to the time chart, it also displays the relative volume of an activity on Twitter about the topic. as you can see there is a spike about GSLV launch after 3 PM today.There is also a short cut link “Now” on the left corner which displays the latest results on the topics searched.The tweets also gets refreshed automatically.   Considering the huge volume of activity (50 million messages per day) on twitter, the archive is going to more and bigger. By providing such feature Google has once again proved it is way ahead of others in search Related Posts:None FoundJoin us on Facebook to read all our stories right inside your Facebook news feed.

  • uninstall google chrome in fedora

    - by tbleckert
    Yesterday I installed Fedora 15 Beta with GNOME 3 - it works well. One problem though is that I installed Chrome 32-bit (which was wrong, should have been the 64-bit version) and now I can't uninstall it. I can't find it in Add/Remove Software, and I also can't install the correct version of Chrome because it complains about my other copy of Chrome. Any ideas how I can remove the existing copy and get the 64-bit version installed?

To interact with google docs I am aware that a token is requested from google upon authentication and verification of the account however that is in a situation where you code specifically for interacting with google docs - I'm talking about having access to the google docs of the account which has added my application so my application can be used to upload documents to the google docs and make references to them - basically my application is a resource management application and it needs to be able to store references to google docs.

  • GAE Datastore: persisting referenced objects

    - by David
    Two "I'm sorries" to begin with: 1) I've looked for a solution (here, and elsewhere), and couldn't find the answer. 2) English is not my mother tongue, so I may have some typos and the sort - please ignore them. To the point: I am trying to persist Java objects to the GAE datastore. I am not sure as to how to persist object having ("non-trivial") referenced object. That is, assume I have the following. public class Father { String name; int age; Vector<Child> offsprings; //this is what I call "non-trivial" reference //ctor, getters, setters... } public class Child { String name; int age; Father father; //this is what I call "non-trivial" reference //ctor, getters, setters... } The name field is unique in each type domain, and is considered a Primary-Key. In order to persist the "trivial" (String, int) fields, all I need is to add the correct annotation. So far so good. However, I don't understand how should I persist the home-brewed (Child, Father) types referenced. Should I: Convert each such reference to hold the Primary-Key (a name String, in this example) instead of the "actual" object. So, Vector<Child> offsprings; becomes Vector<String> offspringsNames; ? If that is the case, how do I handle the object at run-time? Do I just query for the Primary-Key from Class.getName, to retrieve the refrenced objects? Convert each such reference to hold the actual Key provided to me by the Datastore upon the proper put() operation? So, Vector<Child> offsprings; becomes Vector<Key> offspringsHashKeys; ? I would very much appreciate all kinds of comments. I have read ALL the offical relevant GAE docs/example. Throughout, they always persist "trivial" references, natively supported by the Datastore (e.g. in the Guestbook example, only Strings, and Longs). Many thanks, David

  • Google Script / Spreadsheet -- Shared permissions with Installed Trigger onEdit

    - by user1761852
    Using an installed trigger inside spreadsheet to call onUpdateBilling(). Purpose of this script is on edit, based on content of column "billed" (i.e. "d") will highlight the entire column the predetermined color. Page running script is shared with collaborators and they have been given edit access. My expectation at this point is the script should be run with owner permissions. My shared users are unable to run the script with the given error "You don't have permission for this action." Reached my limited knowledge and googlefu for this workaround. Any help to allow operation to my collaborators is appreciated.

  • Using Property Builtin with GAE Datastore's Model

    - by ejel
    I want to make attributes of GAE Model properties. The reason is for cases like to turn the value into uppercase before storing it. For a plain Python class, I would do something like: Foo(db.Model): def get_attr(self): return self.something def set_attr(self, value): self.something = value.upper() if value != None else None attr = property(get_attr, set_attr) However, GAE Datastore have their own concept of Property class, I looked into the documentation and it seems that I could override get_value_for_datastore(model_instance) to achieve my goal. Nevertheless, I don't know what model_instance is and how to extract the corresponding field from it. Is overriding GAE Property classes the right way to provides getter/setter-like functionality? If so, how to do it? Added: One potential issue of overriding get_value_for_datastore that I think of is it might not get called before the object was put into datastore. Hence getting the attribute before storing the object would yield an incorrect value.
