![]() ![]() let us know if you your workflow needs a view that has one layer that join both origin and destination layer. note, the relationshipId for both layer is the same.įYI we also support creating a view that joins both layers. In the Example below, you will need to define the relationship for each layer which reference that other layer. This API can only allow you to create a relationship between the two layers and be able to use queryRelated API on the layer. The origin layer and its related layer (table) has to exist. We do support add relationship to existing feature service in online using feature service addToDefinition API. "composite" : // // Not sure if you need composite but set it to false if you do not need it "relatedTableId" : 0, // This is the layerId of the origin "name" : "myRel", // use the same name you defined above for the relationship name. "composite" : // Not sure if you need composite but set it to false if you do not need it "keyField" : "", // Origin primary key like GlobalId if the relationship based on globalId "cardinality" : "esriRelCardinalityOneToMany", ![]() "relatedTableId" : 1, // (table or related layer Id) "name" : "myRel", // for your relationshp. You just need to replace these in the example json I sent you. Primary key in the origin layer (field name that acts as a primary key) >Also, how am I defining what the 2nd layer is? As in, a pointer to the name of the 2nd layer (table) so it knows which >table is related? I do not see any such reference in your sample.Īll what you really need to figure out is the followings: The json you have used in your last message is not correct. send me the full url (strip the token) and the json used. Only what I have included in my example is needed. Will work with the team to get this documented.īut you will need to follows the example I have sent you. The following steps will allow your application to access to an Web Map.Sorry this is not documented well so I could not find the doc for you to use. To find the id, view your web map in and notice that the URL includes the unique map identifier. When a map is shared, the author decides what to include with the map. You can share them through links or embed them in websites, and use them to create map-based web apps. In the left-panel, click Basemap to close the window. You can create maps in a few basic steps and open them in standard web browsers, mobile devices, and desktop map viewers. A blank basemap pane is added to the project. In the left-panel, click Basemap > Current Basemap > Streets. In the Project group, click the arrow on the New Map button and choose New Basemap. Open the Map Viewer and sign into your ArcGIS account. Use the Streets vector tile basemap layer. You can share them through links or embed them in websites, and use them to create map-based web apps. To create a web map with the Map Viewer, start by setting the basemap layer. To build a web map visit the Create a map tutorial.Īfter creating the web map copy the web map id for use in the rest of this tutorial. You can create maps in a few basic steps and open them in standard web browsers, mobile devices, and desktop map viewers. Sometimes a reference map service that contains boundaries or labels is placed on top of the other layers to create a "map sandwich": two reference layers with the "meat", or operational data, in between. Web maps typically display a map service with operational data (such as available stands of timber) on top of a map service with reference information (such as imagery or a shaded relief map). These maps share information not just data. They may explain where people are buying homes, where sea surface temperature is changing, or where elephants migrate in the summer. The Map Viewer allows you to quickly and easily create and share web maps that tell interesting stories about your data. Before you begin, if you are new to the ArcGIS API for JavaScript, please read our Setting up a Development Environment topic which covers prerequisites such as setting up a web server and using various IDEs and text editors. ![]()
