in the OSM api I can get information for a way doing this:
/api/0.6/way/#id
I'd like to know how that way changed during time, for instance I'd like to know when the way changed name, etc.. This is interesting to study the evolution of territory..
There is a version="" property on the way, but how can I get older versions?
Check this LINK
You can get the history of a given element by this:
GET /api/0.6/[node|way|relation]/#id/history

I am trying to modify an existing XML package of Aspdotnetstorefront Multistore. It's an internal XML package to show the variants of a certain product. What I did to start with was to copy-paste the whole code as is and throw it into a new custom XML package. The problem is that it works fine in the original package but not in the copied package. When I try to run it the function "AddtoCartForm" crashes the page and show the following error while display in red the line that contains the function call:
An HtmlHelper is required for this method. Make sure to specify one when you call the RunXmlPackage method
The format of the function is:
<xsl:value-of select="aspdnsf:AddtoCartForm(ProductID, VariantID, 1, 1, $SelectedSize, $SelectedColor)" disable-output-escaping="yes"/>
I removed the line with the function just to be sure and then everything else works fine. I have no idea what's wrong here. Everything is identical unless by the structure of the url which calls the package:
For the internal package it is: \product\123456
For the custom package it is: \topic\packagename?ProductID=123456
I checked the XML produced by the SPs, the runtime and requested data and it's basically the same in both cases. The ProductID and VariantID values are there. SelectedColor and SelectedSize are not in the XML (not even in the internal package) so it may be just providing null value and probably it's not necessary anyway.
And there is more. If I supress the productid value from the url like this:
\topic\packagename
It won't crash the page (but also won't render because there will be not be any value to process).
In any way I cannot see why it wouldn't work just passing the variable in the querystring (that is basically what it does in the original package even in a different format) and the var value (productid) it getting there. However it seems that it is indeed the url format that is not pleasing the package but it doesn't make too much sense to me. I am over this for several days already and nothing I do seem to produce any positive result. :-(
I looked up online for some documentation but didn't get lucky and didn't find absolutely anything. In extreme cases I try to reach the Vortx support (and they usually answers me giving some valueable clue) but this time it seems that for this specific issue there will not be any help unless I pay an obscene hour fee and unfortunately it's out of question... LoL!
Any idea?
UPDATE: We don't use Multistore regular search tool. Due to the nature of our products (recycled car parts) we have a custom search tool that will try to find 'similar' items that MAY fit the user needs when we don't have the EXACT part. I don't know if you are ware of but several mechanical car parts are interchangeable among different models and makes (like alternators, AC compressors, battery, suspension, cooling system, etc), so when one of our customers needs a part to fix his car he won't tell us the part code; instead he will tell us the car model, year, and generic name of the part so we will try to find the part for him. It does mean that a certain Corolla part will fit perfectly in a Honda Accord and so on. Some times we have some parts in stock that MAY fit his car but we are not absolutely sure. When it happens we will show those parts for the customer and he will decide if he can take his chances. For the sake of customer comfort we want to show all these parts in the same page, but since they normally are variants of different products we cannot use the regular product page for this purpose (because the product page will only show variants of ONE product at time). For this reason I am going to write a package - a modified version of the product page - that will do that but I am struggling with the AddtoCartForm function. In fact I JUST found a workaround by adding the item to the cart accessing directly the /shoppingcart/addtocart script and now my problem is being to force it return to a specific url after to add the item to the shopping cart...
The error has to do with the topic token able to properly get html helper filled out.
I do question why testing is being done on a topic. To test a new product xmlpackage I normally change change the xmlpackage for just one product in a testing environment.
If chaning the product xmlpackage isn't possible then I suggest using the XmlPackageController/engine instead. Which is documented on page https://help.aspdotnetstorefront.com/1000/xml_packages.htm under the heading of "Invoking XML Packages by Themselves". If using the XmlPackageController make certain that the allowengine attribute is set to true in the xmlpackage otherwise that will throw an error as well.
Is there a way to get the list of available translations for the current selected language at runtime?
I miss something like $translate.getTranslations()
I don't know any way of doing this in runtime. The best you can do is to generate a list using https://github.com/angular-translate/grunt-angular-translate or something similar and then access that list with Ajax.
I am working on a project based on CKAN, and I am required to list in a page all the datasets that have the state "active" and "draft". When you go to the datasets page, you can only see the ones that have the state marked as "active", but not "draft".
If I use the API (call the package_list() method) or REST calls (http://localhost/api/3/action/package_list), CKAN only returns "active" datasets, but not "drafts". I double and triple checked the documentation, and apparently one cannot lists the datasets by their state.
Does anybody have a clue on how to do this? Has anybody done this already?
Thanks!
If nothing else, you could write an extension to do this. The database call itself will be pretty simple:
SELECT id,title,name FROM package WHERE state='active' OR state='draft';
I managed to modify CKAN core to list the datasets that do not have the state "draft" or "deleted", and it works, but I do no want to touch CKAN's core, I want to do this using a plugin, so the normal thing to do is to implement plugins.IActions and override the package_list method with a custom one. I have already written my own extension to try to modify CKAN behavior on method package_list(), but I can't seem to figure it out how to make it work.
Here is my code:
#side_effect_free
def package_list_custom(context, data_dict=None):
datasets = []
dataset_q = (model.Session.query(model.Package)
.join(model.PackageRole))
for dataset in dataset_q:
if dataset.state != 'draft' and dataset.state != 'deleted':
datasets.append(dataset)
return [dataset.id for dataset in datasets]
class Cnaf_WorkflowPlugin(plugins.SingletonPlugin):
plugins.implements(plugins.IActions)
def get_actions(self):
return {
'package_list' : package_list_custom
}
If I modify CKAN core it works very well, but the problem is that I am not to touch it, so I am obliged to do it via an extension.
EDIT: Ok, I managed to make it work, you need to decorate the method with #side_effect_free. I modified my code, and now it works.
The package_search API is capable of this, by searching for state:draft and setting the include_drafts=True flag. Something like this:
https://my-site.com/api/action/package_search?q=state:draft&include_drafts=True
You should be able to access this from a plugin with something like: ckan.plugins.toolkit.get_action('package_search')(context=context, data_dict={'q': 'state:draft', 'include_drafts': True}) (you'll need to assemble the context yourself, containing a 'user' key for the current username and a 'userobj' key for the current user object).
Then make a page from the results.
I've found a public domain latin<->portuguese dictionary in PDF which I'd like to convert to plain text, parse and use as the database of a program. After some testing, however, I got a little skeptical. Take a look at the original file and at the resulting text of gocr. Is there any hope that I might reach 99%+ accuracy in some method? I thought of reCaptcha's database, but I guess it is Google's property, isn't it?
Thanks!
Another route is to use one of the freely available dictionary files, like http://www.brothersoft.com/downloads/dictionary-database.html
Or WordNet.
EDIT: I've just spotted that this is a Latin/Portuguese dictionary, so WordNet clearly is no good.
Does anyone know how to override the GetTileLayers for a collection in the MultiScaleTileSource class. I want to set the source to a xml document ( which is a deep zoom collection doc ). I need to remap where the images come from and the filename format.
This is simple with a single image, but how do you do it for a collection?
Anyone?
thanks

It might not be officially possible. Check out this thread.
A related question might be why the tileImageLayerSources argument of MultiScaleTileSource.GetTileLayers is not specifically a collection of Uris and why is it a collection... i.e. why would we want to add multiple Uris in one call?
The easiest way to do "dynamic" deep zoom is instead of setting the source for the MSI directly to the XML, set it to an ASPX handler that returns the xml you generate on the fly. If you're not sure what I'm saying, let me know and I can reply with more detail.
