  • Emailing a picture to a Google App Engine site

    - by Dan Hook
    I would like to create an app such that I can send an email with a JPEG attachment and then display it on my site. I am fairly certain that the Mail API allows me to do this, but if it isn't possible please let me know. My biggest concern is what are the limits on the attachment size my app can receive, and what are the quotas related to receiving email? The email quotas I saw seemed to specify quotas for outgoing email. Is it different for incoming mail?

  • Google App Engine Python Datastore

    - by python appengine
    Basically what Im trying to make is a data structure where it has the users name, id, and datejoined. Then i want a "sub-structure" where it has the users "text" and the date it was modified. and the user will have multiple instances of this text. class User(db.Model): ID = db.IntegerProperty() name = db.StringProperty() datejoined = db.DateTimeProperty(auto_now_add=True) class Content(db.Model): text = db.StringProperty() datemod= db.DateTimeProperty(auto_now_add = True) Is the code set up correctly?

  • Visual source safe headaches - Deleting files

    - by maxp
    I will pre-empt and say we are stuck using VSS here so changing it is not an option. Anyway, one person, 'user a' is deleting a file from their project. They then do a 'get latest' on the folder and it doesn't come back, so the user assumes they have truely deleted it from the project. We have another user, 'user b', who then looks at 'pending checkins', sourcesafe will then do a scan of all the files in 'user b's project. It then wants to 're-add' all of the files user a deleted. This has caused a huge headache for the team. Any suggestions to stop this from happening again?

  • google app engine db.Model in python only display user-defined fields

    - by MattM
    I'm a python newbie so I apologize in advance if this question has been asked before. I am building out an application in GAE and need to generate a report that contains the values for a user-defined subset of fields. For example, in my db model, CrashReport, I have the following fields: entry_type entry_date instance_id build_id crash_text machine_info I present a user with the above list as a checkbox group from which they select. Whichever fields the user selects, I then create a report showing all the values in the datastore, but only for the fields that they selected. For example, if from the above list, the user selects the build_id and crash_text fields, the output might look like this: build_id crash_text 0.8.2 blown gasket 0.8.2 boom! 0.8.1 crack! ... So the question is, how exactly do I only access the values for the fields which the user has defined?

  • Many-to-Many Relationship (with properties) in Google App Engine for Java

    - by rvandervort
    I understand from the official documentation on unowned relationships that the app must use sets of Key objects on either side of the relationship. This makes perfect sense. Coming from many years of RDBM-style programming, though, I'm pretty confused about how I can model properties of that relationship itself. For example, if I have entities Category and Entry in my many-to-many relationship and would like to persist a dateAdded property, or some other data that are only relevant when both sides of the relationship are known. I suppose it would be possible to create a third class : CategoryEntry that links the two, but this seems like a kludge. What is the proposed way to model this kind of situation ?

  • Google App Engine: Which is its RDBMS?

    - by Vimvq1987
    According to this: http://code.google.com/appengine/docs/whatisgoogleappengine.html it seems that GAE only uses Datastore to store data, which is equivalent with Table service on Windows Azure Platform. Does anyone know that which RDBMS it uses? or such thing exists or not?

  • Google App Engine + AWS S3 file protection!

    - by grep
    Hi all, I have an application running on GAE/J that streams video from AWS S3. I need a solution for protecting the video from being stolen and I found that pre-signed URLs might be it (??). How can I create pre-signed URLs from GAE/J or there's a better solution to secure the videos? thanks

  • Google App Engine: Difficulty with Users API (or maybe just a Python syntax problem)

    - by Rosarch
    I have a simple GAE app that includes a login/logout link. This app is running on the dev server at the moment. The base page handler gets the current user, and creates a login/logout url appropriately. It then puts this information into a _template_data dictionary, for convenience of subclasses. class BasePage(webapp.RequestHandler): _user = users.get_current_user() _login_logout_link = None if _user: _login_logout_link = users.create_logout_url('/') else: _login_logout_link = users.create_login_url('/') _template_data = {} _template_data['login_logout_link'] = _login_logout_link _template_data['user'] = _user def render(self, templateName, templateData): path = os.path.join(os.path.dirname(__file__), 'Static/Templates/%s.html' % templateName) self.response.out.write(template.render(path, templateData)) Here is one such subclass: class MainPage(BasePage): def get(self): self.render('start', self._template_data) The login/logout link is displayed fine, and going to the correct devserver login/logout page. However, it seems to have no effect - the server still seems to think the user is logged out. What am I doing wrong here?

  • Google app engine-php: script handler

    - by Eve
    I try to create php web app using GAE. In the GAE tutorial, "A script handler executes a PHP script to handle the request that matches the URL pattern. The mapping defines a URL pattern to match, and the script to be executed" Now I want to map the url with the file having same name in the folder, e.g. if the url is /hello.* , it will map the file name hello.php in the folder. And if it is /hello1.*, hello1.php in the folder will be responded to the server. I thought this should be done directly by mapping the name of the url with the name in the folder. But if I left empty for the handler in the app.yaml, I got an error. So I want to know how to set up the handler in app.yaml?

  • app-engine-rest-server to raise KeyError("name %s already used" % model_name)

    - by fx
    I'm playing with the project appengine-rest-server to create the REST webservices for all the existing models. I got a strange error, the first time I query the browser: http://localhost:8080/rest/metadata/user, it gives me the result: <xs:schema> - <xs:element name="user"> - <xs:complexType> - <xs:sequence> <xs:element maxOccurs="1" minOccurs="0" name="key" type="xs:normalizedString"/> <xs:element maxOccurs="1" minOccurs="0" name="surname" type="xs:string"/> <xs:element maxOccurs="1" minOccurs="0" name="firstname" type="xs:string"/> <xs:element maxOccurs="1" minOccurs="0" name="ages" type="xs:long"/> <xs:element maxOccurs="1" minOccurs="0" name="sex" type="xs:boolean"/> <xs:element maxOccurs="1" minOccurs="0" name="updatedDate" type="xs:dateTime"/> <xs:element maxOccurs="1" minOccurs="0" name="createdDate" type="xs:dateTime"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> But refreshing the page, gives me this error: Traceback (most recent call last): File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 3185, in _HandleRequest self._Dispatch(dispatcher, self.rfile, outfile, env_dict) File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 3128, in _Dispatch base_env_dict=env_dict) File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 515, in Dispatch base_env_dict=base_env_dict) File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 2387, in Dispatch self._module_dict) File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 2297, in ExecuteCGI reset_modules = exec_script(handler_path, cgi_path, hook) File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 2195, in ExecuteOrImportScript script_module.main() File "/Users/foo/Documents/AppEngine/helloworld/main.py", line 48, in main rest.Dispatcher.add_models({"user": UserModel}) File "/Users/foo/Documents/AppEngine/helloworld/rest/__init__.py", line 845, in add_models cls.add_model(model_name, model_type) File "/Users/foo/Documents/AppEngine/helloworld/rest/__init__.py", line 863, in add_model raise KeyError("name %s already used" % model_name) KeyError: 'name user already used' Can someone give me the explanation on why it happens? Restarting the server, run on the browser again I get the xml result, but refreshing causes the error. Is it a bug in the appengine-rest-server application or it is in my code? My helloworld application is available for download here.

  • ASP.NET MVC, Web API, Razor and Open Source

    - by ScottGu
    Microsoft has made the source code of ASP.NET MVC available under an open source license since the first V1 release. We’ve also integrated a number of great open source technologies into the product, and now ship jQuery, jQuery UI, jQuery Mobile, jQuery Validation, Modernizr.js, NuGet, Knockout.js and JSON.NET as part of it. I’m very excited to announce today that we will also release the source code for ASP.NET Web API and ASP.NET Web Pages (aka Razor) under an open source license (Apache 2.0), and that we will increase the development transparency of all three projects by hosting their code repositories on CodePlex (using the new Git support announced last week). Doing so will enable a more open development model where everyone in the community will be able to engage and provide feedback on code checkins, bug-fixes, new feature development, and build and test the products on a daily basis using the most up-to-date version of the source code and tests. We will also for the first time allow developers outside of Microsoft to submit patches and code contributions that the Microsoft development team will review for potential inclusion in the products. We announced a similar open development approach with the Windows Azure SDK last December, and have found it to be a great way to build an even tighter feedback loop with developers – and ultimately deliver even better products as a result. Very importantly - ASP.NET MVC, Web API and Razor will continue to be fully supported Microsoft products that ship both standalone as well as part of Visual Studio (the same as they do today). They will also continue to be staffed by the same Microsoft developers that build them today (in fact, we have more Microsoft developers working on the ASP.NET team now than ever before). Our goal with today’s announcement is to increase the feedback loop on the products even more, and allow us to deliver even better products.  We are really excited about the improvements this will bring. Learn More You can now browse, sync and build the source tree of ASP.NET MVC, Web API, and Razor on the http://aspnetwebstack.codeplex.com web-site.  The Git repository on the site is the live RC milestone development tree that the team has been working on the last several weeks, and the tree contains both the runtime sources + tests, and is buildable and testable by anyone.  Because the binaries produced are bin-deployable, this allows you to compile your own builds and try product updates out as soon as they are checked-in. You can also now contribute directly to the development of the products by reviewing and sending feedback on code checkins, submitting bugs and helping us verify fixes as they are checked in, suggesting and giving feedback on new features as they are implemented, as well as by submitting code fixes or code contributions of your own. Note that all code submissions will be rigorously reviewed and tested by the ASP.NET MVC Team, and only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source. Summary All of us on the team are really excited about today’s announcement – it has been something we’ve been working toward for many years.  The tighter feedback loop is going to enable us to build even better products, and take ASP.NET to the next level in terms of innovation and customer focus. Thanks, Scott P.S. In addition to blogging, I use Twitter to-do quick posts and share links. My Twitter handle is: @scottgu

  • What's the canonical way to acknowledge many FOSS sources in a single project?

    - by boost
    I have a project which uses a large number of LGPL, Artistic and other open-source licensed libraries. What's the canonical (i.e. the "standard") way of acknowledging multiple sources in a single project download? Also, some of the sources I've used are from sites where using the code is okay, but publishing the source isn't. What's the usual manner of attribution in that case, and the usual manner of making the source available in an open-source project?
