I am trying to change the database table prefix and schema for ABP.IO (https://www.abp.io/). I have found two properties for it but not sure where to change to affect everything. Does anyone have an idea?
The properties:
Volo.Abp.Data.AbpCommonDbProperties.DbTablePrefix
Volo.Abp.Data.AbpCommonDbProperties.DbSchema
You can find them under YourProject.Domain project, YourProjectDbProperties.cs file.
You fix value for Volo.Abp.Data.AbpCommonDbProperties.DbTablePrefix Volo.Abp.Data.AbpCommonDbProperties.DbSchema and re-migrate and update-database.
My way:
Volo.Abp.Data.AbpCommonDbProperties.DbTablePrefix = "Myprefix"
Volo.Abp.Data.AbpCommonDbProperties.DbSchema = null;

I have created a new index that is populated using an indexer. The indexer's datasource is a SQL view that has a Timestamp column of type datetime. Since we don't want a full reindexing each time the indexer runs, this column should be used to determine which data have changed since the last indexer run.
According to the documentation we need to create or update the datasource by setting the HighWatermarkColumnName and ODataType to the DataChangeDetectionPolicy object. The example in the documentation uses the REST API and there is also way to do it using the azure search portal directly.
However I want to do it using .netsdk and so far I haven't been able to do so. I am using Azure.Search.Documents(11.2.0 - beta.2). Here is the part of the code I use to create the datasource:
SearchIndexerDataSourceConnection CreateIndexerDataSource()
{
var ds = new SearchIndexerDataSourceConnection(DATASOURCE,
SearchIndexerDataSourceType.AzureSql,
this._datasourceConStringMaxEvents,
new SearchIndexerDataContainer(SQLVIEW));
//ds.DataChangeDetectionPolicy = new DataChangeDetectionPolicy();
return ds;
}
The commented code is what I tried to do to initialize the DataChangeDetectionPolicy but there is no ctor exposed. Am I missing something?
Thanks in advance.
Instead of using DataChangeDetectionPolicy, you will need to use HighWaterMarkChangeDetectionPolicy which is derived from DataChangeDetectionPolicy.
So your code would be something like:
ds.DataChangeDetectionPolicy = new HighWaterMarkChangeDetectionPolicy("Timestamp");
I need to support database logging.
For that I decided to use nlog because it brings database support.
But first of all I need to setup the configuration programatically.
As far as I understood it I have to set the layout for the target.
But the class "DatabaseTarget" does not have any property related to Layout :/.
var dbTarget = new DatabaseTarget();
dbTarget.ConnectionString = LogConnectionString;
dbTarget.CommandType = System.Data.CommandType.StoredProcedure;
dbTarget.CommandText = "exec dbo.InsertLog #level=${level}, #callSite=${callsite}, #message=${message}, #stackTrace=${stacktrace}, #machinename=${machinename}, #processname=${processname}";
Is the layout definition really necessary for the DatabaseTarget. If so how do I set it programatically?
Additionally I want to pass some information. But I am not sure how I can assign those informations for the procedure.
As far as I understood it I can assign those variables:
https://github.com/nlog/nlog/wiki/Layout-Renderers
But NLog support generic arguments with his Log Method. It looks like this:
_nLog.Log<AJourFaultLevel>(ConvertLogLevel(logEntry.Level), logEntry.Message, logEntry.Fault);
How can I assign the passed "logEntry.Fault" value for my stored procedure?
Best regards
Your current log-statement injects logEntry.Fault as parameter into string.Format(logEntry.Message, logEntry.Fault):
_nLog.Log<AJourFaultLevel>(ConvertLogLevel(logEntry.Level), logEntry.Message, logEntry.Fault);
If you are using NLog 4.5 then you can use structured-logging where you can name the parameter like this:
_nLog.Log<AJourFaultLevel>(ConvertLogLevel(logEntry.Level), "Fault occurred: {AJourFaultLevel}", logEntry.Fault);
Then you can access the named parameter using ${event-properties:item=}:
dbTarget.CommandText = "exec dbo.InsertLog #level=${level}, #callSite=${callsite}, #message=${message}, #stackTrace=${stacktrace}, #machinename=${machinename}, #processname=${processname}, #faultLevel=${event-properties:item=AJourFaultLevel}";
This must be something very simple, I just don't see it (and can not find the answer :(
I am trying to learn DevExpress controls and have read that eXpress Persistent Objects is recommended for O/R mapping.
1) I have an existing SQL Server Compact 4.0 database for which I generated ORM
2) I have a Winform with XtraGrid.GridControl gridControl1
3) In Form_Load event I have this code:
XPCollection cName = new XPCollection(typeof(WindowsFormsApplication1.DUzskv1r6.XPO_TableName));
int c = cName.Count; //didn't help...
cName.DisplayableProperties = "Name;Nr"; //choose columns to display
gridControl1.MainView.PopulateColumns();
gridControl1.DataSource = cName;
I have read that it using "delayed loading" - loading when it is necessary (http://documentation.devexpress.com/#XPO/clsDevExpressXpoXPCollectiontopic), but reading XPcollections record Count didn't do the trick as it was suggested.
As a result I get an empty gridControl1 with columns "Name" and "Nr".
Please help - what am I missing?
I think the issue is somewhere in your datalayer initialization.
You use XPCollection with default session, maybe you forgot to initialize it.
The best way is to specify the session is in the XPCollection contractor.
I found this article useful when indexing documents, however, how can I attach additional fields so I can pass in, say, the ID of the document in our database for use in displaying the search results? I thought by using the Fields (Of the ExtractParameters class) property I could index additional data with the document, but that doesn't seem to work or that is not its function.
Example code:
var solr = ObjectLocator.Instance.Resolve<ISolrOperations<IndexDocument>>();
var guid = Guid.NewGuid().ToString();
using (var fileStream = System.IO.File.OpenRead(Server.MapPath("~/files/") + "greenroof.pdf"))
{
var response =
solr.Extract(
new ExtractParameters(fileStream, "greenRoof1234")
{
ExtractFormat = ExtractFormat.Text,
ExtractOnly = false,
Fields = new[] { new ExtractField("field1", "value1"), new ExtractField("field2", "value2") }
});
}
#aitchnyu is correct, passing the values via the literal.field=value method is the correct way to do this.
However, according to this post on ExtractingRequestHandler support in the SolrNet Google Group, there was a bug with the ExtractParameters.Fields not working properly. This was fixed in the 0.4.0.X versions of SolrNet. Please make sure you are using one of the latest versions of SolrNet. You can obtain that by one of the following means:
Project Site Downloads
NuGet PreRelease Package
Also that discussion has some good examples of using the ExtractingRequestHandler in SolrNet as well as a workaround for adding the additional field values if you cannot upgrade to a newer version of SolrNet.
This is sufficient: http://wiki.apache.org/solr/ExtractingRequestHandler#Literals .
In general use a literal.field=value while uploading.
It turned out not to be an issue with SOLRNet, but my knowledge of SOLR, in general. I needed to specify the fields in my schema. After i added the fields to my schema they were visible in my SOLR query.
I've been having problems with uploading images and in trying to fix it, happened to change the base_url in the config which has now caused my website to appear without any styling at all (inc the Admin).
I've gone into phpMyAdmin and fixed the urls but i'm not having any luck. This is what i've got at the moment...
web/unsecure/base_link_url http://www.northwalesdoorworld.co.uk/
web/unsecure/base_skin_url http://www.northwalesdoorworld.co.uk/skin/
web/unsecure/base_media_url http://www.northwalesdoorworld.co.uk/media/
web/unsecure/base_js_url http://www.northwalesdoorworld.co.uk/js/
Could someone please take a look at my site - northwalesdoorworld.co.uk - and recommend a way to solve my problem?
thanks,
Greg.
if you can't access your site due that you can change the values directly in core_config_data table
SELECT * FROM core_config_data WHERE path LIKE '%web/unsecure%' or path LIKE '%web/secure%'
you can fix them by editing the values to be like clockworkgeek suggested or removing whole rows from database and they will be created over again by magneto and you can use the admin page to add new values.
Change the four values to:
{{unsecure_base_url}}
{{unsecure_base_url}}skin/
{{unsecure_base_url}}media/
{{unsecure_base_url}}js/
Empty var/cache/ in your magento folder.
Please refer to the most recent Magento wiki entry: http://www.magentocommerce.com/wiki/recover/restore_base_url_settings
You can also add something like this to /MAGENTO/app/etc/config.xml rather than manipulate the database:
<stores>
<default>
<web>
<unsecure>
<base_url>{{base_url}}</base_url>
<base_link_url>{{unsecure_base_url}}</base_link_url>
<base_web_url>{{unsecure_base_url}}</base_web_url>
<base_skin_url>{{unsecure_base_url}}skin/</base_skin_url>
<base_js_url>{{unsecure_base_url}}js/</base_js_url>
<base_media_url>{{unsecure_base_url}}media/</base_media_url>
</unsecure>
<secure>
<base_url>{{base_url}}</base_url>
<base_web_url>{{secure_base_url}}</base_web_url>
<base_link_url>{{secure_base_url}}</base_link_url>
<base_js_url>{{secure_base_url}}js/</base_js_url>
<base_skin_url>{{secure_base_url}}skin/</base_skin_url>
<base_media_url>{{secure_base_url}}media/</base_media_url>
</secure>
</web>
</default>
</stores>
