  • ORM solutions (JPA; Hibernate) vs. JDBC

    - by Grasper
    I need to be able to insert/update objects at a consistent rate of at least 8000 objects every 5 seconds in an in-memory HSQL database. I have done some comparison performance testing between Spring/Hibernate/JPA and pure JDBC. I have found a significant difference in performance using HSQL.. With Spring/Hib/JPA, I can insert 3000-4000 of my 1.5 KB objects (with a One-Many and a Many-Many relationship) in 5 seconds, while with direct JDBC calls I can insert 10,000-12,000 of those same objects. I cannot figure out why there is such a huge discrepancy. I have tweaked the Spring/Hib/JPA settings a lot trying to get close in performance without luck. I want to use Spring/Hib/JPA for future purposes, expandability, and because the foreign key relationships (one-many and many-many) are difficult to maintain by hand; but the performance requirements seem to point towards using pure JDBC. Any ideas of why there would be such a huge discrepancy?

  • What is the "owning side" in an ORM mapping?

    - by Yousui
    Hi guys, I'm new to JPA. Now I have a question that what exactly is the owning side mean? I only have a rough idea of it. Can someone give me an explanation with some mapping examples(one to many, one to one, many to one) please? Great thanks. ps, the following text is excerpt from the decription of @OneToOne in java EE 6 documentation. You can see the concept owning side in it. Defines a single-valued association to another entity that has one-to-one multiplicity. It is not normally necessary to specify the associated target entity explicitly since it can usually be inferred from the type of the object being referenced. If the relationship is bidirectional, the non-owning side must use the mappedBy element of the OneToOne annotation to specify the relationship field or property of the owning side.

  • ORM on iPhone. More simple than CoreData.

    - by Alexander Babaev
    The question is rather simple. I know that there is SQLite. There is Core Data also. But I need something in between. More object-oriented than SQLite API and simplier than Core Data. Main points are: I need access to stored entities only by id. No queries required. I need to store items of a single type, it means that I can use only one table if I choose SQLite. I want automatic object-relational conversion. Or object-storage if the storage is not relational. I can use object archiving, but I have to implement things (NSArchiver). But I want to write some kind of class and get persistence automatically. As it can be done with Hibernate/ActiveRecord/Core Data/etc. Thanks.

  • 400 error with nginx subdomains over https

    - by aquavitae
    Not sure what I'm doing wrong, but I'm trying to get gunicorn/django through nginx using only https. Here is my nginx configuration: upstream app_server { server unix:/srv/django/app/run/gunicorn.sock fail_timeout=0; } server { listen 80; return 301 https://$host$request_uri; } server { listen 443; server_name app.mydomain.com; ssl on; ssl_certificate /etc/nginx/ssl/nginx.crt; ssl_certificate_key /etc/nginx/ssl/nginx.key; client_max_body_size 4G; access_log /srv/django/app/logs/nginx-access.log; error_log /srv/django/app/logs/nginx-error.log; location /static/ { alias /srv/django/app/data/static/; } location /media/ { alias /wrv/django/app/data/media/; } location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; proxy_set_header Host $http_host; proxy_pass http://app_server; } } I get a 400 error on app.mydomain.com, but the app is published on mydomain.com. Is there an error in my configuration?

  • Copied Netbeans IDE Maven Web project failes to compile

    - by Quaternion
    If I am going to make serious changes to my project I like to make a copy (right click project and select copy). I have created copies of my projects many times (maven web applications included) without issue. Now all I do is copy the project making no changes, leaving the copy settings on default (project name etc) and then try to run it and spring decides to take issue with it. Again I try running the original and it works. I deleted the faulty copy, restarted and tried again and still it does not work. Here are my maven/system details: Apache Maven 2.2.1 (rdebian-4) Java version: 1.6.0_20 Java home: /usr/lib/jvm/java-6-openjdk/jre Default locale: en_CA, platform encoding: UTF-8 OS name: "linux"

  • How to implement Template Inheritance (like Django?) in PHP5

    - by anonymous coward
    Is there an existing good example, or how should one approach creating a basic Template system (thinking MVC) that supports "Template Inheritance" in PHP5? For an example of what I define as Template Inheritance, refer to the Django (a Python framework for web development) Templates documentation: http://docs.djangoproject.com/en/dev/topics/templates/#id1 I especially like the idea of PHP itself being the "template language", though it's not necessarily a requirement. If listing existing solutions that implement "Template Inheritance", please try to form answers as individual systems, for the benefit of 'popular vote'.

  • Grails benchmarks compared to other web MVC platform (Rails, Django, ASP MVC)?

    - by fabien7474
    I have been searching the web for recent benchmarks measuring Grails overall performance compared to its competitors (Rails, Django, ASP.NET MVC...), but I didn't find anything more recent than a 3 years-old article with obsolete grails version (0.5). See here and here. So, starting from grails 1.2, are there any more recent grails benchmarks you are aware of ? Or do you have your own performance tests for grails (compared to others if possible) ?

  • OperationalError "unable to open database file" processing query results with SQLAlchemy and SQLite3

    - by Peter
    I'm running into this little problem that I hope is just a dumb user error. It looks like some sort of a size limit with a query to a SQLite database. I managed to reproduce the issue with an in-memory DB and a simple script shown below. I can make it work by either reducing the number of records in the DB; or by reducing the size of each record; or by dropping the order_by() call. I am using Python 2.5.5 and SQLAlchemy 0.6.0 in a Cygwin environment. Thanks! #!/usr/bin/python from sqlalchemy.orm import sessionmaker import sqlalchemy import sqlalchemy.orm class Person(object): def __init__(self, name): self.name = name engine = sqlalchemy.create_engine('sqlite:///:memory:') Session = sessionmaker(bind=engine) metadata = sqlalchemy.schema.MetaData(bind=engine) person_table = sqlalchemy.Table('person', metadata, sqlalchemy.Column('id', sqlalchemy.types.Integer, primary_key=True), sqlalchemy.Column('name', sqlalchemy.types.String)) metadata.create_all(engine) sqlalchemy.orm.mapper(Person, person_table) session = Session() session.add_all([Person("012345678901234567890123456789012") for i in range(5000)]) session.commit() persons = session.query(Person).order_by(Person.name).all() print "count =", len(persons) session.close() The all() call to the query result fails with the OperationalError exception: Traceback (most recent call last): File "./stress.py", line 27, in <module> persons = session.query(Person).order_by(Person.name).all() File "/usr/lib/python2.5/site-packages/sqlalchemy/orm/query.py", line 1343, in all return list(self) File "/usr/lib/python2.5/site-packages/sqlalchemy/orm/query.py", line 1451, in __iter__ return self._execute_and_instances(context) File "/usr/lib/python2.5/site-packages/sqlalchemy/orm/query.py", line 1456, in _execute_and_instances mapper=self._mapper_zero_or_none()) File "/usr/lib/python2.5/site-packages/sqlalchemy/orm/session.py", line 737, in execute clause, params or {}) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/base.py", line 1109, in execute return Connection.executors[c](self, object, multiparams, params) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/base.py", line 1186, in _execute_clauseelement return self.__execute_context(context) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/base.py", line 1215, in __execute_context context.parameters[0], context=context) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/base.py", line 1284, in _cursor_execute self._handle_dbapi_exception(e, statement, parameters, cursor, context) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/base.py", line 1282, in _cursor_execute self.dialect.do_execute(cursor, statement, parameters, context=context) File "/usr/lib/python2.5/site-packages/sqlalchemy/engine/default.py", line 277, in do_execute cursor.execute(statement, parameters) sqlalchemy.exc.OperationalError: (OperationalError) unable to open database file u'SELECT person.id AS person_id, person.name AS person_name \nFROM person ORDER BY person.name' ()

  • Dependency Injection and Unit of Work pattern

    - by sunwukung
    I have a dilemma. I've used DI (read: factory) to provide core components for a homebrew ORM. The container provides database connections, DAO's,Mappers and their resultant Domain Objects on request. Here's a basic outline of the Mappers and Domain Object classes class Mapper{ public function __constructor($DAO){ $this->DAO = $DAO; } public function load($id){ if(isset(Monitor::members[$id]){ return Monitor::members[$id]; $values = $this->DAO->selectStmt($id); //field mapping process omitted for brevity $Object = new Object($values); return $Object; } } class User(){ public function setName($string){ $this->name = $string; //mark modified by means fair or foul } } The ORM also contains a class (Monitor) based on the Unit of Work pattern i.e. class Monitor(){ private static array modified; private static array dirty; public function markClean($class); public function markModified($class); } The ORM class itself simply co-ordinates resources extracted from the DI container. So, to instantiate a new User object: $Container = new DI_Container; $ORM = new ORM($Container); $User = $ORM->load('user',1); //at this point the container instantiates a mapper class //and passes a database connection to it via the constructor //the mapper then takes the second argument and loads the user with that id $User->setName('Rumpelstiltskin');//at this point, User must mark itself as "modified" My question is this. At the point when a user sets values on a Domain Object class, I need to mark the class as "dirty" in the Monitor class. I have one of three options as I can see it 1: Pass an instance of the Monitor class to the Domain Object. I noticed this gets marked as recursive in FirePHP - i.e. $this-Monitor-markModified($this) 2: Instantiate the Monitor directly in the Domain Object - does this break DI? 3: Make the Monitor methods static, and call them from inside the Domain Object - this breaks DI too doesn't it? What would be your recommended course of action (other than use an existing ORM, I'm doing this for fun...)

  • Recommend good shared hosting [closed]

    - by Django Reinhardt
    It seems that everyone has something bad to say about the "big" shared hosting sites like 1and1, HostGator, GoDaddy, etc. but what are the ones you've had GOOD experiences with? I'm going to focus this question on LAMP stacks, given that they're the most popular option for shared hosting, but if you have an especially good experience with a different stack. Good shared hosting should be: Competitively priced - But not at the expense of... Fully featured - Email, PHP, MySQL, but what else? Highly customizable - Do you have access to advanced features like being able to deliver static content? Up to date - Do they run PHP4 as standard, or do they run the latest version? Customer service - When you have a problem are they rude and unhelpful? Do they take ages to reply? So how about it? Who have YOU have a good experience with?

  • 1and1: Unable to host an external domain

    - by Django Reinhardt
    I'm sorry if this isn't the right place for this question, but I'm presently having difficulties with my hosting provider (1and1). Two weeks ago, two of my clients bought hosting from them on my recommendation, but as it turned out, 1and1 are having severe technical difficulties. Right now non of their hosting packages are able to accept ANY external domains. So either you pay the costs of transferring the registrar of your domain, or you use the ugly 1and1 domain name. Not any good for a hosting company of 1and1's reputation! They have been promising me for two weeks that they're going to fix the problem, but as you have probably guessed by now, that hasn't been the case. I would like to know if a) Anyone else is in the same boat as me, and b) If there are other comparably reputable hosting providers that I should consider moving to instead? Very disappointing! :( Note: This is for 1and1 in the UK. I imagine it isn't affecting users in other countries(?) Clarification: 1and1 are unable to accept ANY external domains. That means that even if you update your DNS details on your domain, their system cannot be updated to add your external domain to your account.

  • Photo gallery for Blogspot blog

    - by Django Reinhardt
    I don't think this is entirely possible, but here we go: I have a friend who has a Blogspot blog. He has posts with text, posts with videos and posts with photos... and he was wondering if there's any way to turn the posts which are just photos into a thumbnail gallery screen on his blog. So for example, let's say he has 20 photo posts on his blog with the label Skiing Holiday 2009 (horrible example, I know). Is there a way of having a post created for his blog that displays those photos as thumbnails, linking through to their full size versions? I just don't think it's possible, but I'm really hoping someone will be able to offer a solution (or even a place where I could find a solution). Thanks a lot.

  • What are good Python and/or Django deployment solutions?

    - by e-satis
    For now I use some mix between virtual_env, pip and Fabric. This allows to: install required libs; generate dynamic content; isolate installation; push everything through ssh. It works well, I just want to know if there are other tools around. The only problem I could think of is that it's a lot of to set up every time. It doesn't solve database / media files migration issues either, but maybe I should just open another question for this specific subject. Eventually, I don't know how to automatize the server setup. I'd love to have a tool to let me configure Apache/Lighttp/Cherokee and MySQL automatically. Related : How django projects can be deployed with minimal installation works?

  • Issues running python scripts in Command Prompt (Specifically with command line arguments)?

    - by dmanatunga
    I am trying to run my python scripts in DOS without calling python.exe first. I am specifically doing this in relation to running django-admin.py. I have C:\Python26 and C:\Python26\Scripts in my PATH. However, if I try running django-admin.py by doing: django-admin.py startproject helloworld I get the message: Type 'django-admin.py help' for usage. Now, after some experimentation, I realized the problem is that the secondary arguments to these scripts are not being passed for some reason, since I tried it with a some other python scripts I have. I know I could avoid this problem by simply doing: python C:\Python26\Scripts\django-admin.py startproject helloworld But I know it should be possible to run the first command only and get it to work, because I had it working before. I've looked everywhere, and not many places have been helpful so any idea would be useful for me at this point.

  • apache permission errors

    - by Wilduck
    I'm trying to set up Apache on a arch-linux box as a testing environment (I'm only using the localhost, not trying to serve anything to the greater web). When setting up Django with mod_wsgi, it recommended that I set up a WSGIScriptAlias from / to /usr/local/django/mysite/apache/django.wsgi . I've done this, as well as added the /usr/.../apache directory to my httpd.conf. When I try to access http://localhost I get a 403 forbidden error. I have no idea why this is happening. Things I've tried so far: 1) chown -R http .../apache 2) chmod -R 777 .../apache 3) using a simple Alias directive to host a static file from that directory. None of these have worked. I'm at a loss for what I'm doing wrong. Below is a relevant excerpt from my httpd.conf: Alias / /usr/local/django/mysite/apache <Directory "/usr/local/django/mysite/apache"> Order deny,allow Allow from all </Directory> So my question is: what am I doing wrong?

  • Eclipse Pydev Ctrl-Click (Go to Definition) Doesn't Work OSX

    - by Koobz
    My Pydev set up in OS X is kind of busted. I'm working on a Django project and I find that Ctrl-Click never actually goes to the definitions of any of my objects or functions. I actually have a symlink to Django/django in my workspace so that it's easier to cross reference Django code. My guess is that something is wrong with the builder, but it doesn't throw up any errors. Does anyone have advice here? Different topic: does anyone know of a good way to use Ctrl-Shift-R (Open resource) and filter files by folder? It's not that useful in python projects where you have 20 urls.py showing up.

  • SIMPLEST way to set up password protection for a static site, with basic admin UI?

    - by Joseph Turian
    I have a static site. I would like the simplest approach to password protecting a directory, with a basic admin UI for adding/removing users. I will have so few users that I don't care about performance. I don't care if it's PHP or Django or whatever, I just want a complete software package. Apache basic auth isn't good, because you can't log out. Nor is there a UI for adding users. I tried throwing everything behind Django auth and serving the files through Django. However, Chrome treats all my text/css headers as text/plain, so I don't get any stylesheets showing. I can't use mod_xsendfile on my server because I can't reconfigure Apache to add new modules. I think this approach is overkill anyway. I can try configuring Nginx's X-Accel-Redirect, however that requires implementing all the Django code for auth myself, and I'd prefer an existing solution. However, this is my backup plan. Is there a code package that implements authentication with basic admin for a static site?

  • UndeclaredThrowableException due to SQLException in Spring + iBatis?

    - by jr
    Hello, I am getting the following exception when I typo the SQL driver name or the database server is offline, basically any SQLException. I can't determine where the UndeclaredThrowableException is coming from. Line 194 in SqlMapClientTemplate is this: logger.debug("Obtained JDBC Connection [" + springCon + "] for iBATIS operation"); Here is the trace: java.lang.reflect.UndeclaredThrowableException $Proxy59.toString(Unknown Source) java.lang.String.valueOf(Unknown Source) java.lang.StringBuffer.append(Unknown Source) org.springframework.orm.ibatis.SqlMapClientTemplate.execute(SqlMapClientTemplate.java:194) org.springframework.orm.ibatis.SqlMapClientTemplate.executeWithListResult(SqlMapClientTemplate.java:249) org.springframework.orm.ibatis.SqlMapClientTemplate.queryForList(SqlMapClientTemplate.java:296) org.springframework.orm.ibatis.SqlMapClientTemplate.queryForList(SqlMapClientTemplate.java:290) some of my reading points to some type of class loading problem? I can't figure out where the $Proxy is getting introduced?

  • How do I create self-relationships in polymorphic inheritance in Elixir and Pylons?

    - by Turukawa
    I am new to programming and am following the example in the Pylons documentation on creating a Wiki. The database I want to link to the wiki was created with Elixir so I rewrote the Wiki database schema and have continued from there. In the wiki there is a requirement for a Navigation table which is inherited by Pages and Sections. A section can have many pages, while a page can only have one section. In addition, each sibling node can be chain-referenced to each other. So: Nav has "section" (OneToMany) and "before" (OneToOne - to reference preceeding node) Page has "section" (ManyToOne - many pages in one section) and inherits "before" Section inherits all from Nav The code I've written looks like this: class Nav(Entity): using_options(inheritance='multi') name = Field(Unicode(30), default=u'Untitled Node') path = Field(Unicode(255), default=u'') section = OneToMany('Page', inverse='section') after = OneToOne('Nav', inverse='before') before = OneToMany('Nav', inverse='after') class Page(Nav): using_options(inheritance='multi') content = Field(UnicodeText, nullable=False) posted = Field(DateTime, default=now()) title = Field(Unicode(255), default=u'Untitled Page') heading = Field(Unicode(255)) tags = ManyToMany('Tag') comments = OneToMany('Comment') section = ManyToOne('Nav', inverse='section') class Section(Nav): using_options(inheritance='multi') Errors received on this: sqlalchemy.exc.OperationalError: (OperationalError) table nav has no column named aftr_id u'INSERT INTO nav (name, path, aftr_id, row_type) VALUES (?, ?, ?, ?)' I've also tried: before = ManyToMany('Nav', inverse='before') on Nav in the hopes this might break the problem, but also not. The original SQLAlchemy code from the tutorial for these declarations is as follows: nav_table = schema.Table('nav', meta.metadata, schema.Column('id', types.Integer(), schema.Sequence('nav_id_seq', optional=True), primary_key=True), schema.Column('name', types.Unicode(255), default=u'Untitled Node'), schema.Column('path', types.Unicode(255), default=u''), schema.Column('section', types.Integer(), schema.ForeignKey('nav.id')), schema.Column('before', types.Integer(), default=None), schema.Column('type', types.String(30), nullable=False) ) page_table = schema.Table('page', meta.metadata, schema.Column('id', types.Integer, schema.ForeignKey('nav.id'), primary_key=True), schema.Column('content', types.Text(), nullable=False), schema.Column('posted', types.DateTime(), default=now), schema.Column('title', types.Unicode(255), default=u'Untitled Page'), schema.Column('heading', types.Unicode(255)), ) section_table = sa.Table('section', meta.metadata, schema.Column('id', types.Integer, schema.ForeignKey('nav.id'), primary_key=True), ) orm.mapper(Nav, nav_table, polymorphic_on=nav_table.c.type, polymorphic_identity='nav') orm.mapper(Section, section_table, inherits=Nav, polymorphic_identity='section') orm.mapper(Page, page_table, inherits=Nav, polymorphic_identity='page', properties={ 'comments':orm.relation(Comment, backref='page', cascade='all'), 'tags':orm.relation(Tag, secondary=pagetag_table) }) Any help is much appreciated.

  • STL member variable initalization issue with windows API

    - by Django
    I am creating a windows app that uses a vector of stings as a member variable. For some reason, I can compile but when it tries to get at any of the vectors members is crashes. the error is 0xC0000005: Access violation reading location 0xcdcdcdd9. in the member function of the vector class. this is the size() function where it breaks. size_type capacity() const { // return current length of allocated storage return (this->_Myend - this->_Myfirst); } I am using visual studios 2010. thank you Django
